However, this is not a Cygwin version but native Windows then.

Sigh.  I want Cygwin support for a real Cygwin version of tcc which will
understand Cygwin mounts and so on.  A native Windows version is already
available.  To build this just use the provided support, just one change
in config.mak is needed, instead of
CC=i386-mingw32-gcc
AR=i386-mingw32-ar
use this
CC=gcc -mno-cygwin
AR=ar

$ ./configure --enable-mingw32 --prefix='/as/you/like/it'
$ make

This builds also the library.


No other changes needed for the native Windows version.
Well, not really, `make test` fails to compile the test with tcc, this
needs to be fixed.

Once real Cygwin support is included I would include tcc in the Cygwin
netrelease.
