I just tried building on all of these combinations:

Solaris 10: compilers 6.2 and 11
Solaris 9: compilers 8, 9, 10, 11
Solaris 8: compilers 6.2, 9, 11

Postgresql 8.1.3 fails to compile on all of them with --enable-debug

I can run this back to older compilers as well, if needed.

none that I'm aware of.

It's been a decade since I've done any serious sparc assembler, but my
first thought on seeing this C code was that the .section directives
didn't belong. Perhaps they might have been needed on SunOS4 systems,
but I don't think it was.

Either way, add an -xO0 with --enable-debug if you really want to keep
the directives, but that's just masking the underlying problem.
