PATCH: Provide stdint.h for Tru64 UNIX V[45]

[Rainer Orth <ro at CeBiTec dot Uni-Bielefeld dot DE>]

The following patch implements stdint.h for Tru64 UNIX V4 and V5.  I've
chosen to include the definitions in alpha/osf.h directly instead of
using a separate alpha/osf-stdint.h instead, just like e.g. Solaris 2.

Bootstrappped without regressions on alpha-dec-osf4.0f and
alpha-dec-osf5.1b.

There's one testsuite problem I'd like to get an opinion about:
gcc.dg/c99-stdint-6.c is unsupported on alpha-dec-osf4.0f, which lacks
inttypes.h completely, but FAILs on alpha-dec-osf5.1b which has an
incomplete inttypes.h, i.e. without definitions for *int_least*_t,
*int_fast*t, *intmax_t.  I could either augment the header via
fixincludes, or XFAIL the test on V5.1B.  Preferences?

I'll check the patch as osf maintainer, but would like to wait for
opinions on the issue above before doing so.

	Rainer
