Are you sure it's not a bug in mksh, and in which version anyway?  The 
stdarg testcases from the testsuite all work just fine.

I can also build mksh-R48b with tcc just fine:

% uname -a
% cd /matz/git/tinycc; git log --online HEAD^..
767410b Various Makefile fixes for cross-compilation
% ./configure; make; make test
... all works ...
% cd /tmp/
% tar xvf mksh-R48b.tgz
% mkdir mksh/build; cd mksh/build
% CC="/matz/git/tinycc/tcc -B/matz/git/tinycc/" /bin/sh ../Build.sh
...
Run the regression test suite: ./test.sh
Please also read the sample file dot.mkshrc and the fine manual.
% ./mksh ./test.sh
...
Total failed: 0
Total passed: 466

So, if you want anything fixed we'd first need to know what is broken, 
e.g. a testcase ;)


Ciao,
Michael.
