Interrupts / Remove int31 handler from msdos

Sat Nov 16 12:56:47 CST 2002
This patch finally deletes INT_Int31Handler and associated functions
from msdos/int31.c. Next patches will concentrate on removing dead code
from other msdos/*.c files and cleaning up .spec and .h files referencing
the removed functions.
Changelog:
Removed obsolete INT_Int31Handler.
