The problem seems to come to the fact that

  --with-gmp-build=DIR    GMP build directory (please read INSTALL file)

is listed after

  --with-gmp=DIR          GMP install directory

by "./configure --help". If I switch these lines, everything works
as expected. There's no reason to depend on the order of the options
listed by "./configure --help". So, this seems to be a bug somewhere
in the zsh completion system.
