I've built a new MinGW package 5.1.4.1 for PPM that includes the forwarder
for windres.exe.
I found a somewhat surprising WTF in the MinGW installer itself: even though
the version number is unchanged at 5.1.4 the following 3 included packages
have been updated from the last time I downloaded it:
from: binutils-2.17.50-20060824-1.tar.gz
to: binutils-2.19.1-mingw32-bin.tar.gz
from: mingwrt-3.15.1-mingw32.tar.gz
to: mingwrt-3.15.2-mingw32-dev.tar.gz
from: w32api-3.12-mingw32-dev.tar.gz
to: w32api-3.13-mingw32-dev.tar.gz
If you have any contact with the MinGW developers you may want to mention
that updating the version number of MinGW might be a good idea. I would
have expected that at least the "Build" number would be changed in the
mingw.ini file, but even that remained at "11".
The 5.1.4.1 PPM package will have all the "latest" bits, so you may want
to give it a spin. It may take a day or two before it becomes visible on
the external PPM server.

I've added that code, and also tried to use it for the ActivePerl::Config
hack that tells ExtUtils::Liblist::Kids about the MinGW library location:

This should make it easier to eventually get the changes back into the CPAN
version. Do you see any problem with pushing the MinGW/lib directory to
the end of LIBRARY_PATH even though GCC will already have this location
built in? I'll do some testing before the next release myself, but feel
free to try it and see if you find any problems with this.
Cheers,
