OK.  However, the expectation is that my --with specification would override
the default behavior.  Perhaps, the test should be for $with_gd/bin/gdlib-c=
onfig
first, if fails then try in $PATH.  I quickly tested the following and it
seems to work.  (I'm not well versed in this configure script stuff but
I gave it a try).

  if test -d "$with_gd"; then
    if test -n "$with_gd/bin/gdlib-config"; then
      libgd_CPPFLAGS=3D`$with_gd/bin/gdlib-config --cflags`
      libgd_LDFLAGS=3D"-L$with_gd/lib "`$with_gd/bin/gdlib-config --ldflags`
    else
      libgd_CPPFLAGS=3D"-I$with_gd/include"
      libgd_LDFLAGS=3D"-L$with_gd/lib"
    fi
  else
    AC_PATH_PROG([GDLIB_CONFIG], [gdlib-config])
    if test -n "$GDLIB_CONFIG"; then
      libgd_CPPFLAGS=3D`gdlib-config --cflags`
      libgd_LDFLAGS=3D`gdlib-config --ldflags`
    fi
  fi

There still is the issue of testing for the fontconfig library.=20=20
There is not a unique function that can be tested for.  I see
that gdlib-config can list the libraries it requires.
