libgomp just doesn't configure any more on Tru64 UNIX V5.1B:
configure: error: Pthreads are required to build libgomp
This is due to the last configure.ac change:
2006-07-05 Eric Christopher <[EMAIL PROTECTED]>
* configure.ac: Depend addition of -pthread on host OS.
* configure: Regenerate.
which list the -pthread flag during the compile test, so both pthread tests
fail now:
configure:8315: /vol/gcc/obj/gcc-4.2.0-20060705/5.1b-gcc/./gcc/xgcc
-B/vol/gcc/obj/gcc-4.2.0-20060705/5.1b-gcc/./gcc/

conftest.c >&5

/vol/gcc/obj/gcc-4.2.0-20060705/5.1b-gcc/./gcc/include/pthread.h:339:4: error:
#error "Please compile the module including pthread.h with -pthread"
Before that patch, -pthread was included and the test succeeded.
I think this tweaking of pthread detection in libgomp must stop: this
introduces problems all over the place. I suppose there are some tested
autoconf macros to achieve this correctly on all platforms.
