[Tru64 UNIX V5.1] gcc testsuite fixes


With the patches in

http://gcc.gnu.org/ml/gcc-patches/2001-02/msg01448.html (still unreviewed)
http://gcc.gnu.org/ml/gcc-patches/2001-02/msg01451.html (already integrated)

I'm able to bootstrap gcc 3.0 20010221 (prerelease) on both Tru64 UNIX
V4.0F and V5.1.  Comparing the test results for both O/S releases

http://gcc.gnu.org/ml/gcc-testresults/2001-02/msg00380.html (V4.0F)
http://gcc.gnu.org/ml/gcc-testresults/2001-02/msg00381.html (V5.1)

I find only a few differences (some are described in a separate message):

In gcc.log, I find that compilation fails with a linker error:

/usr/bin/ld:
Warning: nan defined as GLOBAL DATA but is defined in a shared lib as a GLOBAL FUNC

This is fixed by the patch below, which allows me to compile all tests, yet
fp-cmp-2.x? and fp-cmp-3.x? still fail:

* fp-cmp-2.x0 fails the fnan == fnan test in line 23

* fp-cmp-3.x0 fails the dnan != x test in line 27

	* gcc.c-torture/execute/ieee/fp-cmp-1.c: Renamed nan to dnan.
	* gcc.c-torture/execute/ieee/fp-cmp-3.c: Likewise.
	* gcc.c-torture/execute/ieee/fp-cmp-2.c: Renamed nan to fnan.
