{
  possible compiler switches (* marks a currently required switch):
  -----------------------------------------------------------------
  USE_RHIDE           generates errors and warning in an format recognized
                      by rhide
  TP                  to compile the compiler with Turbo or Borland Pascal
  GDB*                support of the GNU Debugger
  I386                generate a compiler for the Intel i386+
  M68K                generate a compiler for the M68000
  USEOVERLAY          compiles a TP version which uses overlays
  EXTDEBUG            some extra debug code is executed
  SUPPORT_MMX         only i386: releases the compiler switch
                      MMX which allows the compiler to generate
                      MMX instructions
  EXTERN_MSG          Don't compile the msgfiles in the compiler, always
                      use external messagefiles, default for TP
  NOAG386INT          no Intel Assembler output
  NOAG386NSM          no NASM output
  -----------------------------------------------------------------

  Required switches for a i386 compiler be compiled by Free Pascal Compiler:
  GDB;I386

  Required switches for a i386 compiler be compiled by Turbo Pascal:
  GDB;I386;TP

  Required switches for a 68000 compiler be compiled by Turbo Pascal:
  GDB;M68k;TP
