>Environment:
Linux ia64. RedHat-7.2, RHAS-2.1, Debian Sarge
>Description:
gcc's documented "-pthread" option does not set the -D_REENTRANT pre-processor flag.
the link flag -lpthread is correctly set.
"-pthread" is supposed to be a front-end to any needed options / libraries needed in order to build a multi-thread program. This includes pre-processing, compilation & link.

1. get the attached program pthbug.c
