I just checked the size of insn-attrtab.c, it's actually 1.4GB! :S

I forgot to mention that this is a cross-compiler I'm building for the ARM target on my Mac.
On my Mac, I have gcc-4.0 and gcc-4.2.
gcc builds fine for ARM, but I do not yet know if it builds for Mac/PowerPC.

2 questions:
1: Wouldn't gcc-4.5 [by default, that is] have the same malloc-problem as 4.2 ?
2: Doesn't Apple compile gcc in a special way, so that it differs from a standard ./configure && make install ?

Anyway, I'm trying (once again) to compile gcc for Mac/PowerPC


Love,
