I do lots of work with Watcom, so I can tell you about those three
lines. I can't tell you how to convert them to DJGPP V2, though.

These lines tell the Watcom compiler about the register usage of the
procedure. It takes parameter #1 in ebx, parameter #2 in cx, and
paramter #3 in al. It returns its value in ebx. It modifies only registers
ax, cx, and ebx and does not touch memory.
