You'll end up with sub-directories and fancy make files

Much simpler than many makefiles.

Well yes, but you won't be able to run a parallel make if there are several instances of qvariant. I think it would be better to use an instance-specific subdirectory, say sallysort/qspecif.h, and a -I option on the "cc".

Alternatively, use a macro processor (perhaps even the C preprocessor) to generate sallysort.c from qvariant.c and sallysort.h, then compile.

That said, I do think that James' suggestion can be useful to configure and reuse C source code, or code in other languages (where it may be necessary to separate the macro expansion step from the compilation step).
