So for this to work correctly we need to store the files in the -dev
delivery in the default include and lib directories as well as the
triplet specific directory.  Or maybe supply a -tdev (t for target)
package that lays out files in the appropriate triplet directory.  Or
is there some specification to mingw-get we can suggest the directory
structure for some meta -tdev package using the -dev package for
source?

I would prefer to use i686-pc-mingw and x86_64-pc-mingw instead of
i686-pc-mingw32 and x86_64-pc-mingw64 for the triplets.  I don't see
the importance of retaining the 32 and 64 for the triplet designation.

I would like to suggest the following patch to the config maintainer,
any objection?  I need something better than "It will break my current
environment."; such is the life of programming in an "improving"
world.
