during a build trying gcc-3, i encountered this error (which i think
another person reported, but i can not find that mail):

sparc64/auto-build.h has SIZEOF_LONG as 4 bytes, rather than 8.

If i understand correctly, one has to bootstrap the compiler in
src/tools/gcc to recreate this/these files.  is that correct?

I have not gone through that process yet, so I do not know why
SIZEOF_LONG had the value 4.
