gt-c-pragma.h uses attribute unused in a parameter list, before the
parameter type. Like so:
void sub (__attribute__ ((unused)) int i) { }
This is a syntax that gcc-2.7.2 doesn't support. It was added later.
You could try hacking this out, but it might be simpler to try baby
steps. Use 2.7.2 to compile gcc-2.95.3, use 2.95.3 to compile
gcc-3.3.4, use 3.3.4 to compile gcc-4.x.
I see that 2.95.3 supports this syntax, so it might be able to compile
gcc-4.x, but there may also be other problems, so going from 2.95.e to a
3.x release, and then to a 4.x release is more likely to work.
We could probably fix this with some ifdefs, but gcc-2.7.2 is so old
that it doesn't seem worth the hassle. Plus there are probably other
issues that haven't been noticed yet.
