[fink-core] thoughts on path-prefix

[Benjamin R. <ra...@be...>]

why not take it a step further, and have the "gcc" and "g++" packages be 
part of a replacable package?  ie:

Package: system-gcc3.3
Provides: gcc3.3
Conflicts: system-gcc4, gcc4
Replaces: system-gcc4, gcc4
BuildDependsOnly: true
Files: %p/lib/path-prefix/gcc %p/lib/path-prefix/g++

Package: system-gcc4
Provides: gcc4
Conflicts: system-gcc3.3, gcc4
Replaces: system-gcc3.3, gcc4
BuildDependsOnly: true
Files: %p/lib/path-prefix/gcc %p/lib/path-prefix/g++

This would let a package just BuildDepends: gcc4 or gcc3.3 and get the 
Right Thing in it's path without any work.  It also means the same info 
files would still work on 10.3 because we also have a "gcc4" package 
that could provide the same path-prefix files.

I know there's details that wouldn't work exactly as I have it here, but 
the general idea would make things easier to transition, would it not? 
No need to override the path with gcc3.3 even when people are building 
with gcc_select set to 4.0, instead packages would BuildDepends on the 
right compiler, and if it's not specified, we can default to adding 
system-gcc3.3 to the builddepends.

Thoughts?
