in <42fscp$clr@hasle.oslonett.no> asks:

>I have some code written in C++ that compiles with Borland C++ 4.5.
>This code includes the header <dos.h>, contains interrupt routines and
>calls the function setvect.

>gcc also has a <dos.h> header, but does not seem to include the
>setvect function and the interrupt keyword(?). How can this code be
>ported to compile with gcc?

1. gcc questions are implentation-specific.  You might get a reasonable
answer by asking this question in one of the gnu.* or
comp.os.msdos.djgpp programming newsgroups, but get their FAQ and read
it first.

2. If you retrieve the FAQ from rtfm.mit.edu, you will have a better
idea of the kinds of questions appropriate here.

3. gcc/djgpp is a protected-mode compiler.  Attempts to do real-mode
interrupts are hairy.  You can check the FAQ (faq102.zip) available
where you got gcc, and "info libc" under go32 functions or dpmi
functions.
