I wrote suggesting that djgpp should be able to compile small real-mode
functions and programs (e.g. as interrupt handlers). Someone replied that the
resulting (need to cope with segment-and-offset type addresses in 32bit mode)
would cause too much complication. This complication would be avoided if the
rule said that any djgpp real-mode compilations must all fit (including all
working space) into 64K bytes and thus all in one segment and no heap / malloc
/ new / delete / etc, no recursion, all array bounds to be numeric. This would
be enough to write interrupt handlers and similar without the user having to
clutter his computer with another C compiler to write real-mode odds and ends.
