- {
- 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
- MULLER release special debug code of Pierre Muller
- (needs some extra units)
- 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
- BIG_ENDIAN Target machine where compiler will run is
- a BIG ENDIAN machine (such as m68k)
- -----------------------------------------------------------------
- -----------------------------------------------------------------
-
- 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

- * recompiling of some units in libraries fixed
- * shared libraries are working again
- + $LINKLIB <lib> to support automatic linking to libraries
- + libraries are saved/read from the ppufile, also allows more libraries
- per ppufile
