- XLI support was removed because it was memory-consuming,
and not very performant. You can easily link functions
written in C using the %ESC opcode; see asmlink.c
and escape.c.
- Protected mode Scheme was removed (use SCM if you really need
somthing that doesn't run in real 8086 mode).
- MAKE_FSL.EXE doesn't exist any more.
It is now directly implemented in PCS by the new
FAST-SAVE-FILE function, which is much more convenient.
There are also some weird things happening with MAKE_FSL and
large or floating-point numbers.
