configure --with- completion

[Vincent Lefevre <vincent@xxxxxxxxxx>]

In MPFR, I can do:

  ./configure --with-gmp=[TAB]
  ./configure --with-gmp-include=[TAB]
  ./configure --with-gmp-lib=[TAB]

and complete with directory names, but

  ./configure --with-gmp-build=[TAB]

doesn't allow me to complete with directory names.

FYI, "./configure --with-[TAB]" outputs:

Completing option
--with-gmp              -- GMP install directory
--with-gmp-build        -- GMP build directory (please read INSTALL file)
--with-gmp-include      -- GMP include directory
--with-gmp-lib          -- GMP lib directory
--with-gnu-ld           -- assume the C compiler uses GNU ld (default=no)
--with-mulhigh-size     -- internal threshold table for mulhigh
--with-pic              -- try to use only PIC/non-PIC objects (default=use
--with-sysroot          -- Search for dependent libraries within DIR
--without-gmp           -- GMP install directory
--without-gmp-build     -- GMP build directory (please read INSTALL file)
--without-gmp-include   -- GMP include directory
--without-gmp-lib       -- GMP lib directory
--without-gnu-ld        -- assume the C compiler uses GNU ld (default=no)
--without-mulhigh-size  -- internal threshold table for mulhigh
--without-pic           -- try to use only PIC/non-PIC objects (default=use
--without-sysroot       -- Search for dependent libraries within DIR

and "./configure --help" outputs:

[...]
  --with-gmp-include=DIR  GMP include directory
  --with-gmp-lib=DIR      GMP lib directory
  --with-gmp=DIR          GMP install directory
  --with-gmp-build=DIR    GMP build directory (please read INSTALL file)
[...]

Is there something missing in zsh completion?
