Ok, I got a fix for that. Could you try applying the patch attached to this 
email? Save the patch somewhere and do patch -p1 < 
path/to/patch/macos_mcontext.diff

If this patch is not enough, try adding #define_XOPEN_SOURCE before the 
"#include <sys/ucontext.h>" line in tcc.h and tells me if it makes any 
difference.

As to handling mac os X 10.6 in configure I need the result of uname -s and 
uname -a (just in case). By the way, are you sure macos X 10.6 is only 64 bits 
? Because if it's not the case I need to find a way to differentiate between a 
64 bit macos fainting 32 bit and a real 32 bit one.
