ONLY for people who not are already TOO OLD to type some configure
options or TO TRY something NEW or DIFFERENT, eventually:

# build a cross-tcc using standard cygwin gcc and install in X:

    ./configure --prefix=$PWD/X
    make
    make install
    make distclean

# configure once for using that, anytime in future:

    ./configure --cc=$PWD/X/tcc --prefix=$PWD/W

# build a native windows tcc, optionally with -m32/64, run full tests,
  and install as ready-to-use relocatable tree in W:

    make
    make cross-i386-win32  (cross-x86_64-win32 if on 32bits)
    make test
    make install

-- gr
