Cross Compiling Help

[DtY]

The program compiles fine natively for Linux, but I can't get it to cross compile. (Note, I've never done this before).
I installed these packages: mingw32-SDL mingw32-binutils mingw32-cpp mingw32-gcc using yum (Fedora 10)
When I compile, it tells me:

$ i686-pc-mingw32-gcc -o Flashy.exe flash.c -lSDL
