to disable cancelation at the start of a thread's cancelation
run to prevent double cancelation. The main problem
arises if a thread is canceling and then receives a subsequent
async cancel request.
* private.c: Likewise.
* condvar.c: Place pragmas around cleanup_push/pop to turn
off inline optimisation (/Obn where n>0 - MSVC only). Various
optimisation switches in MSVC turn this on, which interferes with
the way that cleanup handlers are run in C++ EH and SEH
code. Application code compiled with inline optimisation must
also wrap cleanup_push/pop blocks with the pragmas, e.g.
#pragma inline_depth(0)
pthread_cleanup_push(...)
...
pthread_cleanup_pop(...)
#pragma inline_depth(8)
* rwlock.c: Likewise.
* mutex.c: Remove attempts to inline some functions.
* signal.c: Modify misleading comment.

Remove unused autoconf files;
Add the file COPYING, which describes the pthread-win32 license
relative to the FSF LGPL.

* private.c (ptw32_threadStart): Unhandled exceptions are
now passed through to the system to deal with. This is consistent
with normal Windows behaviour. C++ applications may use
set_terminate() to override the default behaviour which is
to call ptw32_terminate(). Ptw32_terminate() cleans up some
POSIX thread stuff before calling the system default function
which calls abort(). The users termination function should conform
to standard C++ semantics which is to not return. It should
exit the thread (call pthread_exit()) or exit the application.
* private.c (ptw32_terminate): Added as the default set_terminate()
function. It calls the system default function after cleaning up
some POSIX thread stuff.
* implement.h (ptw32_try_enter_critical_section): Move
declaration.
* global.c (ptw32_try_enter_critical_section): Moved
from dll.c.
* dll.c: Move process and thread attach/detach code into
functions in nonportable.c.
* nonportable.c (pthread_win32_process_attach_np): Process
attach code from dll.c is now available to static linked
applications.
* nonportable.c (pthread_win32_process_detach_np): Likewise.
* nonportable.c (pthread_win32_thread_attach_np): Likewise.
* nonportable.c (pthread_win32_thread_detach_np): Likewise.
* pthread.h: Add new non-portable prototypes for static
linked applications.
* GNUmakefile (OPT): Increase optimisation flag and remove
debug info flag.
* pthread.def: Add new non-portable exports for static
linked applications.
2000-12-11 Ross Johnson <rpj@special.ise.canberra.edu.au>
* FAQ: Update Answer 6 re getting a fully working
Mingw32 built library.
2000-09-09 Ross Johnson <rpj@special.ise.canberra.edu.au>
* pthread.h (ctime_r): Fix arg.
./tests/ChangeLog:
2000-12-28 Ross Johnson <rpj@special.ise.canberra.edu.au>
* eyal1.c: Increase thread work loads.
* exception2.c: New test.
* exception3.c: New test.
* Makefile: Add new tests exception2.c and exception3.c.
* GNUmakefile: Likewise.
2000-12-11 Ross Johnson <rpj@special.ise.canberra.edu.au>
* cleanup3.c: Remove unused variable.
* cleanup2.c: Likewise.
* exception1.c: Throw an exception rather than use
a deliberate zero divide so that catch(...) will
handle it under Mingw32. Mingw32 now builds the
library correctly to pass all tests - see Thomas
Pfaff's detailed instructions re needed changes
to Mingw32 in the Pthreads-Win32 FAQ.

* errno.c: Add _MD precompile condition; thus far
had no effect when using /MD compile option but I
thnk it should be there.
* exit.c: Add __cplusplus to various #if lines;
was compiling SEH code even when VC++ had
C++ compile options.
* private.c: ditto.
* create.c (pthread_create): Add PT_STDCALL macro to
function pointer arg in _beginthread().
* pthread.h: PT_STDCALL really does need to be defined
in both this and impliment.h; don't set it to __cdecl
- this macro is only used to extend function pointer
casting for functions that will be passed as parameters.
(~PThreadCleanup): add cast and group expression.
(_errno): Add _MD compile conditional.
(PtW32NoCatchWarn): Change pragma message.
* implement.h: Move and change PT_STDCALL define.
* need_errno.h: Add _MD to compilation conditional.
* GNUmakefile: Substantial rewrite for new naming
convention; set for nil optimisation (turn it up
when we have a working library build; add target
"fake.a" to build a libpthreadw32.a from the VC++
built DLL pthreadVCE.dll.
* pthread.def (LIBRARY): Don't specify in the .def
file - it is specified on the linker command line
since we now use the same .def file for variously
named .dlls.
* Makefile: Substantial rewrite for new naming
convention; default nmake target only issues a
help message; run nmake with specific target
corresponding to the EH scheme being used.
* README: Update information; add naming convention
explanation.
* ANNOUNCE: Update information.
2000-08-12 Ross Johnson <rpj@special.ise.canberra.edu.au>
* pthread.h: Add compile-time message when using
MSC_VER compiler and C++ EH to warn application
programmers to use PtW32Catch instead of catch(...)
if they want cancelation and pthread_exit to work.
* implement.h: Remove #include <semaphore.h>; we
use our own local semaphore.h.
tests/ChangeLog:
2000-08-13 Ross Johnson <rpj@special.ise.canberra.edu.au>
* condvar3.c: Minor change to eliminate compiler
warning.
* condvar4.c: ditto.
* condvar5.c: ditto.
* condvar6.c: ditto.
* condvar7.c: ditto.
* condvar8.c: ditto.
* condvar9.c: ditto.
* exit1.c: Function needed return statement.
* cleanup1.c: Remove unnecessary printf arg.
* cleanup2.c: Fix cast.
* rwlock6.c: Fix casts.
* exception1.c (PtW32CatchAll): Had the wrong name;
fix casts.
* cancel3.c: Remove unused waitLock variable.
* GNUmakefile: Change library/dll naming; add new tests;
general minor changes.
* Makefile: Change library/dll naming; add targets for
testing each of the two VC++ EH scheme versions;
default target now issues help message; compile warnings
now interpreted as errors to stop the make; add new
tests; restructure to remove prerequisites needed
otherwise.
* README: Updated.

* pthread.h: Remove #warning - VC++ doesn't accept it.
2000-08-05 Ross Johnson <rpj@special.ise.canberra.edu.au>
* pthread.h (PtW32CatchAll): Add macro. When compiling
applications using VC++ with C++ EH rather than SEH
'PtW32CatchAll' must be used in place of any 'catch( ... )'
if the application wants pthread cancelation or
pthread_exit() to work.
2000-08-03 Ross Johnson <rpj@special.ise.canberra.edu.au>
* pthread.h: Add a base class Pthread_exception for
library internal exceptions and change the "catch"
re-define macro to use it.
2000-08-02 Ross Johnson <rpj@special.ise.canberra.edu.au>
* GNUmakefile (CFLAGS): Add -mthreads.
Add new targets to generate cpp and asm output.

2000-08-05 Ross Johnson <rpj@special.ise.canberra.edu.au>
* cancel2.c: Use PtW32CatchAll macro if defined.
* exception1.c: Use PtW32CatchAll macro if defined.
2000-08-02 Ross Johnson <rpj@special.ise.canberra.edu.au>
* tsd1.c: Fix typecasts of &result [g++ is now very fussy].
* test.h (assert): Return 0's explicitly to allay
g++ errors.
* join2.c: Add explicit typecasts.
* join1.c: Add explicit typecasts.
* join0.c: Add explicit typecasts.

Remove MSVC sections (was commented out).
Add target to generate cpp output.
