Hi Christian,  please read carefully:

    @rem ------------------------------------------------------
    @rem batch file to build tcc using mingw, msvc or tcc itself

Using a cygwin gcc to compile tcc will NOT produce something generally
usable, not in one stage at least.

Also, CONFIG_TCCDIR has no meaning in a correctly compiled tcc for
windows.  It is never used.
