I see. It looks like you didn't run the configure script. The config.h
file should be created during configuration, and the links to the
include files should be set up in the early stages of the build

Why not?  Nothing would stop you from running "CC=my-cc ./configure
--prefix=/usr/local/stow/gsl_my-cc ; make ; make install" to get a
version that's compiled with my-cc. I think trying to compile only
certain parts means asking for trouble, because you'll have to
manually keep track of dependencies during linking. Why not let the
linker figure it out for you?

That's more of less straightforward as things are now. I've managed to
compile large portions with TCC (
