From FreeBSD:
A FreeBSD specific option ... gcc -pthread ....
^^^^^^^^^^^^^^^^
From Solaris 2.6:
POSIX
cc [ flag ... ] file ... -lpthread [ library ... ]
^^^^^^^^^
From Irix 6.5.2f:
cc -D_POSIX_C_SOURCE=199506L app.c -llib0 -llib1 ... -lpthread
^^^^^^^^^
It was just brought to my attention that our use of -lc_r was non-standard.
Solaris, Irix, Linux, and I believe even AIX all use -lpthread.
