Comment:

 More specifically, take `gcc5` for instance. It has this depends line:
 `path:lib/libgcc/libgcc_s.1.dylib:libgcc`.

 This means that, as long as the file
 `${prefix}/lib/libgcc/libgcc_s.1.dylib` exists (which both `libgcc` and
 `libgcc-devel` provide - hence the conflict), the dependency is satisfied.
 Otherwise, libgcc will be installed automatically.

 (CC'ing myself, because I closed the ticket.)
