Results for 4.1.0 20060117 (prerelease) testsuite on powerpc-apple-darwin8.4.0 (-m64 results)

I'm not recommending anything, I'm trying to help you verify whether  
GCC's testsuite is failing because of testsuite bugs, gcc bugs, tools  
bugs, or OS bugs. This should help you focus on the legitimate  
problems with gcc.

In this case, the thousands of failures were an interaction between  
how the testsuite runs the linker with -L paths relative to the  
bootstrapped compiler in the local build directory, and wouldn't be  
seen, typically, if you ran the testsuite against an installed compiler.

As a GCC developer and/or bleeding edge user, it's fairly common to  
require a newer toolchain to support new features in gcc than is  
being officially shipped by Apple. Running the testsuite successfully  
counts as a "feature" in this case. In those cases, you can either  
use binaries posted by members of Apple's compiler team, or build  
odcctools from source. I don't see this as significantly different.

If your concern is that you don't trust the modifications that have  
been made, you can view them and apply only the fixes you want:
