"savant system"?  If you post the complete macro then i can modify
it to be generic for any package.

That's not too bad.  What would be cool is if pccts installed a pkg-config
specification.

i'm just using C (not C++).  Is there really that much boilerplate support
code to justify creating a library?

Dunno.  i'm pretty satisfied already.  A really minor improvement that
would be appreciated is to clean up the generated code a little bit to
avoid triggering so many compiler warnings:
