# - replace gcc, as, ar and ranlib with it's mingw32 equivalents
# - nename -mcpu to -mtune (reduce compiler noise)
# - make windows commands "copy" and "del" to use linux equivalents
# - replace "if exists" with rm -f
# - add x86cpuid to dependencies
# - do not build test programs - they run fine with wine, but are a bit
