Subject: Unconditionally define:
X-Git-Tag: REL9_0_0~12930
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=30a06fe2c4ef63a6b705203b0490486b8f254e6d;p=pg-rex%2Fsyncrep.git

Unconditionally define:

	-D_REENTRANT -D_THREAD_SAFE -D_POSIX_PTHREAD_SEMANTICS

for all ports.  It can't hurt if they are not supported, but it makes
our job easier for porting.

Should fix Darwin compile and other platforms without mucking with the
thread detection code.
