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  <echristo@apple.com>

        * 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/
-B/vol/gcc/share/alpha-dec-osf5.1b/bin/ -B/vol/gcc/share/alpha-dec-osf5.1b/lib/
-isystem /vol/gcc/share/alpha-dec-osf5.1b/include -isystem
/vol/gcc/share/alpha-dec-osf5.1b/sys-include -o conftest -O2 -g -O2  -mieee  
conftest.c  >&5
In file included from conftest.c:25:
/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.

Environment:
System: OSF1 bartok V5.1 2650 alpha
Machine: alpha

host: alpha-dec-osf5.1b
build: alpha-dec-osf5.1b
target: alpha-dec-osf5.1b
configured with: /vol/gcc/src/gcc/configure --prefix=/vol/gcc
--with-local-prefix=/vol/gcc --disable-nls --host alpha-dec-osf5.1b --build
alpha-dec-osf5.1b --target alpha-dec-osf5.1b
--with-gmp-dir=/vol/gnu/obj/gmp-4.1.3
--with-mpfr-dir=/vol/gnu/obj/gmp-4.1.3/mpfr
--enable-languages=c,c++,fortran,java,objc,ada --disable-libmudflap

How-To-Repeat:
Bootstrap mainline as described above.
