I fully agree to what you say here; though one question I have: what do
you mean with 'lack of cross-compilation support' ? Provided that you
use the host pkg-config (means prefix the same as the compiler and other
tools) it should work, no?
With the newer mingw cross compilers it seems to me that it works ...
