Bug#156662: gcc 3.2 will need Depends and Build-Depends on binutils and glibc versions for ppc
severity 156662 wishlist
thanks
these are requirements for future versions. I don't see anything which
would make the current libgcc_s.so.1 from gcc-3.0 worser than it
is. Please correct me if I am wrong.
