I don't understand this remark. Why would that be needed?
The C ABI is well defined on the usual systems, and tcc is compatible 
with the respective compilers. You can link together objects from tcc, 
gcc and icc on Linux /OSX or tcc, MSVC and gcc on Windows without problems.
tcc is *only* the compiler, not a library, so it will call out into the 
C library that Python is using.

tcc even has a "JIT-mode" of operation (libtcc). For Tcl, there exists 
an extension which compiles C code to memory and executes directly from 
there. The same thing could be done for Python, too.
