although what you describe is certainly an issue, it is actually not
what causes gcc to built a 32bit only compiler.

to build a gcc that will accept -m64, you need to build it with
--host=3Dsparc64-sun-solaris (or sparcv9-sun-solaris, which is a synonym
for that).

I was about to raise this issue on tech-pkg shortly, as it may have
some unexpected pkgsrc-wide impact.

grant.
