Cygwin version:

./autogen.sh (coming from CVS need to fix some mistake in makefile under Cygwin if you just do a simple ./configure)

JIT version: 
    ./configure --enable-jit-fpu --enable-jit-compiler --disable-serialport --disable-nfclipbrd
    Correction in makefile: add -O3

Non JIT version with MMU enabled:
    ./configure --disable-serialport --disable-nfclipbrd --enable-fullmmu
    Correction in makefile: add -O3
