No script.  Just:

<from directory in which `pwd`/gcc is the top-level dir of checked out gcc>:
% mkdir devtcc; cd devtcc
% CC="/matz/git/tinycc/tcc -B/matz/git/tinycc/" ../gcc/configure \
  --disable-bootstrap --enable-languages=c,c++,fortran,java,objc
% make -j8

Recent checkouts of GCC will also have the va_arg fix already applied, so it 
should build well out of box with tcc's mob branch.  Note that I checked only 
the above self-build of gcc (i.e. including building its own runtime libs), I 
didn't run the testsuite; weekend was running out :)


Ciao,
Michael.
