Not really. Recent Autoconf has AC_USE_SYSTEM_EXTENSIONS which helps to
enable all those extensions that ought to be unproblematic to have in
parallel, but I don't think _OSF_SOURCE fits that category, and
_XOPEN_SOURCE_EXTENDED probably doesn't either.
Other than that, I've just successfully built the CVS version of GNU
make on Tru64 5.1, with a plain "configure -C", seeing a few warnings of
this kind but no other issues:
source='../make/main.c' object='main.o' libtool=no DEPDIR=.deps depmode=tru64 /bin/ksh ../make/config/depcomp cc -DLOCALEDIR=\"/home/rwild/local/alphaev67-dec-osf5.1/share/locale\" -DLIBDIR=\"/home/rwild/local/alphaev67-dec-osf5.1/lib\" -DINCLUDEDIR=\"/home/rwild/local/alphaev67-dec-osf5.1/include\" -DHAVE_CONFIG_H -I. -I../make -I../make/glob -g -c ../make/main.c
cc: Warning: ../make/main.c, line 987: In this statement, "bsd_signal(...)" of type "int", is being converted to "pointer to function (int) returning void". (cvtdiftypes)
FATAL_SIG (SIGHUP);
--^
The test suite passes, except for those tests that fail due to missing
Cwd.pm in the Perl installation, for example:
*** Test died (features/patternrules): Can't locate Cwd.pm in @INC (@INC contains: /usr/lib/perl-5.005/lib/5.00503/alpha-dec_osf /usr/lib/perl-5.005/lib/5.00503 /usr/lib/perl-5.005/lib/site_perl/5.005/alpha-dec_osf /usr/lib/perl-5.005/lib/site_perl/5.005 .) at scripts/features/patternrules line 7.
BEGIN failed--compilation aborted at scripts/features/patternrules line 7.
Tru64 4.0D gives a similar experience, but completely passes with the
working Perl installation I used there.
Of course, I did have to remove the @MAINT_MAKEFILE@ line from
Makefile.in before the vendor make would accept the Makefile. :-)
Cheers,
Ralf
