I changed VT_SIGNED in VT_DEFSIGN to indicate if the signed used is the 
default one or one that was explicitely given. This way I can see if an 
unsigned char is unsigned because of no signeness specifier or because it was 
declared as unsigned char.

Now arm runs the full test suite without any error with both libgcc and 
libtcc, yeah \o/

I noticed while testing the code that there is 2 errors on i386 with the 
current mob tcc, not due to latest commits. I'd like to debug this and then 
launch a call for testing for tcc 0.9.27 but I'm not well versed in x86 these 
days so if anybody want to try, please do.

Best regards,
