I tested before release on

SunOS t1000 5.10 Generic_118833-17 sun4v sparc SUNW,Sun-Fire-T1000

with gcc-4.0.2 and just tested again, and it works there (except the
final libtool part, but one can use Gforth without that).

How does it fail?  It works on our system:

checking for off_t... yes
checking for off_t... (cached) yes
checking size of off_t... 8

That looks like _RESTRICT_KYWD should be #defined somewhere, but
isn't.  On our system it is defined in sys/feature_tests.h.

You could try to generate the preprocessed file(s) and see which files
the preprocessor included and what else it did.

There seems to be another #define missing (in sys/ccompile.h on our
system).

These are probably followup errors comong from the __NORETURN.

It may be necessary to set certain flags (or avoid setting certain
flags) to activate the #defines, but with the data I have I cannot
give specific advice.
