exit() rather than pthread_exit(). Add comments to explain
why.
* rwlock2_t.c: New test.
* rwlock3_t.c: New test.
* rwlock4_t.c: New test.
* rwlock5_t.c: New test.
* rwlock6_t.c: New test.
* rwlock6_t2.c: New test.
* rwlock6.c (main): Swap thread and result variables
to correspond to actual thread functions.
* rwlock1.c: Change test description comment to correspond
to the actual test.

conditional compilation; refinements; bug fixes. See the ChangeLog.

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

* pthread.h (rand_r): Fake using _seed argument to quell
compiler warning (compiler should optimise this away later).
* GNUmakefile (OPT): Leave symbolic information out of the library
and increase optimisation level - for smaller faster prebuilt
dlls.

* Makefile: fix typo.
* pthreads.h: Fix problems with stdcall/cdecl conventions, in particular
remove the need for PT_STDCALL everywhere; remove warning supression.
* (errno): Fix the longstanding "inconsistent dll linkage" problem
with errno; now also works with /MD debugging libs -
warnings emerged when compiling pthreads library with /MD (or /MDd)
compiler switch, instead of /MT (or /MTd) (i.e. when compiling pthreads
using Multithreaded DLL CRT instead of Multithreaded statically linked
CRT).
* create.c (pthread_create): Likewise; fix typo.
* private.c (ptw32_threadStart): Eliminate use of terminate() which doesn't
throw exceptions.
* Remove unnecessary #includes from a number of modules -
[I had to #include malloc.h in implement.h for gcc - rpj].

* pthread.h (PTHREAD_MUTEX_DEFAULT): New; equivalent to
PTHREAD_MUTEX_DEFAULT_NP.
* (PTHREAD_MUTEX_NORMAL): Similarly.
* (PTHREAD_MUTEX_ERRORCHECK): Similarly.
* (PTHREAD_MUTEX_RECURSIVE): Similarly.
* (pthread_mutex_setdefaultkind_np): New; Linux compatibility stub
for pthread_mutexattr_settype.
* (pthread_mutexattr_getkind_np): New; Linux compatibility stub
for pthread_mutexattr_gettype.
* mutex.c (pthread_mutexattr_settype): New; allow
the following types of mutex:
PTHREAD_MUTEX_DEFAULT_NP
PTHREAD_MUTEX_NORMAL_NP
PTHREAD_MUTEX_ERRORCHECK_NP
PTHREAD_MUTEX_RECURSIVE_NP
* Note that PTHREAD_MUTEX_DEFAULT is equivalent to
PTHREAD_MUTEX_NORMAL - ie. mutexes should no longer
be recursive by default, and a thread will deadlock if it
tries to relock a mutex it already owns. This is inline with
other pthreads implementations.
* (pthread_mutex_lock): Process the lock request
according to the mutex type.
* (pthread_mutex_init): Eliminate use of Win32 mutexes as the
basis of POSIX mutexes - instead, a combination of one critical section
and one semaphore are used in conjunction with Win32 Interlocked* routines.
* (pthread_mutex_destroy): Likewise.
* (pthread_mutex_lock): Likewise.
* (pthread_mutex_trylock): Likewise.
* (pthread_mutex_unlock): Likewise.
* Use longjmp/setjmp to implement cancelation when building the library
using a C compiler which doesn't support exceptions, e.g. gcc -x c (note
that gcc -x c++ uses exceptions).
* Also fixed some of the same typos and eliminated PT_STDCALL as
Milan Gardian's patches above.

* rwlock.c: Revamped.
* implement.h (pthread_rwlock_t_): Redefined.
This implementation does not have reader/writer starvation problem.
Rwlock attempts to behave more like a normal mutex with
races and scheduling policy determining who is more important;
It also supports recursive locking,
has less synchronization overhead (no broadcasts at all,
readers are not blocked on any condition variable) and seem to
be faster than the current implementation [W98 appears to be
approximately 15 percent faster at least - on top of speed increase
from Thomas Pfaff's changes to mutex.c - rpj].

* 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.

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.

* 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.

* rwlock6.c: New test.
