Re: [PATCHES] PostgreSQL libraries - PThread Support, but

Ok guys, I propose that the new libpq diff and 2 source files which
i'll soon send to pgsql-patches is applied to the source. This diff is
a cleaned up version of the previous version with the wrapper
functions moved out into their own file and more comments added. Also
the use of crypt_r() has been removed (not worth the effort), the
cpp defines have been renamed to be consistent with each other and
Tom's concerns with loose #defines has been partly addressed.

This diff does not include any configure changes. I plan to tackle
this separately ASAP, and hopefully produce something more acceptable.

I will add checks for appropriate compiler thread flags (for compiling
libpq, and alow the removal of #defines in libpq-reentrant.h), and
link flags & libs (for a planned threaded libpq test program and
renentrant ecpg library). If a thread environment is found then check
for the reentrant functions will be done.

Looking at various open source projects configure.in files there seems
to be little commonality in the thread test macros (telp gratefully
accepted!), I currently think that something like the approach used by
glib is most suitable (switch on OS).

All sound acceptable?

Thanks, Lee.
