Other have answered about libtcc.h, but why do you want the user to write code 
in C
specifically (as opposed to some higher-level scripting language)?

And in addition of using tinycc & libtcc.h (with tcc_add_file or 
tcc_compile_string), you
also have the possibility of writing the C file into a temporary file foo.c, 
compile it
with optimizations by forking a gcc -fPIC -shared -O -o foo.so foo.c, then 
dlopen-ing the
foo.so (a process can dlopen many thousands *.so files on Linux).

You could also use GNU lightning, libjit, or LLVM to generate machine code....

Cheers.
