relocate? But the regular cygwin gcc needs at least w32api, and that
location is hardcoded in its specs file. Which means that relocate
implies -> respin gcc-3.4.4-999, and respin gcc-4.2.3. And it doesn't
really make sense for the cygwin-gcc specs to specify "always look in
/usr/i686-pc-mingw32/include/[w32api]". Whuh, huh? *-mingw32?
It makes more sense to me that we have two different w32api packages:
the "regular" one that installs into /usr/[include|lib]/w32api, and a
mingw-cross-w32api that installs into
/usr/${mingw-triple}/[include|lib]/[w32api].
mingw-runtime...sure, that could probably be "relocated" without
trouble. I don't think the "regular" cygwin gcc should care about that.
