+ * When USE_COMPILER is defined, a m68k->i386 instruction compiler will be
+ * used. This is experimental. It has only been tested on a Linux/i386 ELF
+ * machine, although it might work on other i386 Unices.
+ * This is supposed to speed up application programs. It will not work very
+ * well for hardware bangers like games and demos, in fact it will be much
+ * slower. It can also be slower for some applications and/or benchmarks.
+ * It needs a lot of tuning. Please let me know your results with this.
+ * The second define, RELY_ON_LOADSEG_DETECTION, decides how the compiler 
+ * tries to detect self-modifying code. If it is not set, the first bytes
+ * of every compiled routine are used as checksum before executing the
+ * routine. If it is set, the UAE filesystem will perform some checks to 
+ * detect whether an executable is being loaded. This is less reliable
+ * (it won't work if you don't use the harddisk emulation, so don't try to
+ * use floppies or even the RAM disk), but much faster.
+ *
+ * @@@ NOTE: This option is unfortunately broken in this version. Don't
