Обсуждение: Patch for: 7.4.2 build broken on Solaris 7 and 8 with --enable-thread-safety

Hi All,

The following patch fixes building PostgreSQL 7.4.2 under Sun (Sparc)
Solaris 7 and 8 (possibly earlier and later versions, as well) with
--enable-thread-safety.

The first addresses what would appear to be a coding error in
thread.c.  The second ensures the proper pthread function call
semantics.

Build tested using GCC 3.3.1 under Solaris 7 and 8.  Tested with
ancient version of Sun's commercial development package under Solaris
8.

Note: I don't know that --enable-thread-safety actually *works* on
these platforms.  But the package now builds.

Regards,
Jim

I have updated the solaris template file in CVS HEAD and 7.4.X to
reflect your changes.  I had already fixed the thread.c typo.

Thanks.
