rev c39bc9c crashed due to assertion (sadly I don't have time to investigate 
further):

Thanks,
this worked (with the latest git revision):

 tcc  -I. -Ilib -Isrc -g -c -o lib/getfilecon.o lib/getfilecon.c

However, I'm not sure how to reliably modify the makefiles of coreutils 
(especially given that gcc,clang handle this situation without a problem).

To be continued,
Thanks,
