Hello Alvaro,

here goes v4 version: removed unused header.

Compilation of this code snippet with -Wall -Wexter -std=c89 doesn't produce any warnings.

Looks great -- it's a lot smaller than the original even. One final
touch -- see cfread(), where we have an #ifdef where we test for
fp->compressedfp; the "#else" branch uses the same code as the
!fp->compressedfp. I think your get_cfp_error can be written more
simply using that form. (Also, your version probably errors or warns
about "code before declaration" in that routine, which is not allowed in
C89.)
