gcc version 3.1
>Description:
When I first configured gcc-3.1 for this machine, the gcc-3.1/lib/gcc-lib/sparc-sun-solaris2.8/3.1/sparcv9/crtfastmath.o file was not installed.  I investigated and discovered that it was not being built as a 64-bit object when building gcc as a 32-bit program (but capable of building 64-bit and 32-bit applications).

It looks like a Makefile issue.  See below.
>How-To-Repeat:
Configure and build gcc-3.1 out of the box...
>Fix:
This patch appeared to fix the problem.
