[SDL] Mingw cross-compile

[Francesco Orsenigo]

I installed mingw cross-compiler from a debian package, and i'd like to use 
it with SDL.

Now, how does a cross compiler work?
How can i tell gcc to create a w32 executable using mingw instead of an ELF?
I have to recompile SDL?
If so, where the new library will be placed?
I will still be able to just add `sdl-config --cflags --libs` to compile both 
ELF and w32?

Thanx,
