+In ptw32_InterlockedCompareExchange.c, I've added a section for
+Borland's compiler; it's identical to that for the MS compiler except
+that it uses /* ... */ comments instead of ; comments.
+
+The other file is a makefile suitable for use with Borland's compiler
+(run "make -fBmakefile" in the directory).  It builds a single version
+of the library, pthreadBC.dll and the corresponding pthreadBC.lib
+import library, which is comparable to the pthreadVC version; I can't
+personally see any demand for the versions that include structured or
+C++ exception cancellation handling so I haven't attempted to build
+those versions of the library.  (I imagine a static version might be
+of use to some, but we can't legally use that on my commercial
+projects so I can't try that out, unfortunately.)
+
+Borland C++ doesn't define the ENOSYS constant used by pthreads-win32;
+rather than make more extensive patches to the pthreads-win32 source I
+have a mostly-arbitrary constant for it in the makefile.  However this
+doesn't make it visible to the application using the library, so if
+anyone actually wants to use this constant in their apps (why?)
+someone might like to make a seperate NEED_BCC_something define to add
+this stuff.
+
+The makefile also #defines EDEADLK as EDEADLOCK, _timeb as timeb, and
+_ftime as ftime, to deal with the minor differences between the two
+RTLs' naming conventions, and sets the compiler flags as required to
+get a normal compile of the library.
+
+
+(While I'm on the subject, the reason Borland users should recompile
+the library, rather than using the impdef/implib technique suggested
+previously on the mailing list, is that a) the errno constants are
+different, so the results returned by the pthread_* functions can be
+meaningless, and b) the errno variable/pseudo-variable itself is
+different in the MS & BCC runtimes, so you can't access the
+pthreadVC's errno from a Borland C++-compiled host application
+correctly - I imagine there are other potential problems from the RTL
+mismatch too.)
+
+Best regards,
