Thanks for the report.  The cause is that libtcc1.a needs to contain 
position independend code as well (so that it may be linked into shared 
libraries).  I've simply added -fPIC for compiling all components of it, 
which should be fine no matter if it's compiled by gcc or tcc.

In any case the default config from tcc (mob branch as of ea2805f0) can 
now build gawk-4.1-stable without shared lib regressions (i.e. filefuncs 
and functab4 now work).  I do see other tests fail as well: backbigs1, 
backsmalls1, mbfw1, mbprintf1 and mbprintf4; which seem to be locale 
dependend, but they work when compiling with gcc on my system.  But seems 
unrelated to shared libs issues.


Ciao,
Michael.
