I have been building gcc-4.0.0 from Apple sources with tags in the

I amended /usr/lib/gcc/powerpc-apple-darwin8/4.0.0/specs
rm -rf /usr/lib/gcc/*/4.0.0/specs
Clearly that is the surgical solution, but what is the file there for?
I have now realised that it is not generated as part of the compiler
build process. In fact it is one of two files in Apple Xcode gcc-4.0
package which is not derived from the source code. The other is "/
Library/Application Support/Xcode/Specifications/GCC 4.0.xcspec" I
now realise the warnings arise because the specs file is from a
different compiler.
Presumably these files serve some purpose. How do they affect the
operation of the compiler?
