Re: [gentoo-dev] Proposal: add a compiler-version entry to pkg db

[Branko Badrljica <brankob@avtomatika.com>]

While at it, it might be useful to have someghing like compiler-use file 
( like package.use) for per-package compiler version and FLAGS to be used.

It is annoying to have emerge -eD world fail because some package 
requires specific compiler version or because gcc-3.4 can't be compiled 
with -march=barcelona or with -combine CFLAGS...
There should also be an option for the user to match compiler with 
compiler version, used to compile some other package. Perhaps with 
naming full name of the package instead of compiler name and version 
string in some file, like /etc/portage/package-infra.use or something 
like that.

That approach could also be used for selecting specific version of 
perl/python/ruby/autotools/whatnot.
