Statically linking C code into ECL

What do you mean by 'linking C file'? If you want to compile independent
C file with ECL, then you are out of luck, because there is no official
support for that in ECL's builder. It may work by passing file as one of
lisp-files to builder, because ECL uses C files *internally*, but it's
far from encouraged or official.
As a side note, I see you use there c::builder, which is also
internal. Exported interfaces are build-fasl, build-program,
build-static-library and build-shared-library (it doesn't make a
difference right now, but in the future builder interface may change,
while the mentioned functions wont).

builder (and all interfaces built on top of it) support ld-flags key
argument. Additionally if you want to influence how ECL compiles files
dynamically you may shadow *user-cc-flags* and *user-ld-flags*.

If this remarks aren't helpful, please tell me exactly what do you want
to achieve with some minimal example (i.e I'm doing that and that,
expecting this and this, but it doesn't work failing in this way),
because I don't quite understand your problem.
I'm adding ecl-devel to CC, because someone may be more competent to
answer your question.
