Okay. I will take down the binaries I have posted for gcc-3.0.1 sparcv9,
and replace them with snapshots of 3.1.
There seems to be lots of demand for 64 bit compilers, most of which
comes from the misunderstanding of the benefits of 64 bit binaries.
My understanding is that 64 bit binaries:
1) Are slower than 32 bit binaries
2) Require a more complicated development environmnet to build.
3) Are larger.
4) Have a much bigger address space.
The only reason I can see to build something 64 bit is if you need the
address space...
