#ifdef VMS

#  ifdef __GNUC__

/*   Names of external functions which contain upper case letters are
 *   modified by the VMS GNU C compiler to prevent confusion between
 *   names such as XOpen and xopen.  GNU C does this by translating a
 *   name like XOpen into xopen_aaaaaaaax with "aaaaaaaa" a hexadecimal
 *   string.  However, this causes problems when we link against the
 *   X library which doesn't contain a routine named xopen_aaaaaaaax.
 *   So, we use #define's to map all X routine names to lower case.
 *   (Note that routines like BlackPixelOfScreen, which are [for VMS]
 *   preprocessor macros, do not appear here.)

/*
 * The names redefined here are those which the current Ghostscript X11
