This already exists, and is very common.

Many software packages have a script called "configure" (not a C
function, though I suppose it could be implemented in C) that can,
for example, generate a C header file containing macro definitions.
The C source code is then compiled using that generated header file.
There's no need to change the language to support pre-compile-time
configuration.
