It is usually best not to mix two separate and unrelated questions in one 
message.  It is also best to choose a better Subject line ;-)

Don't use int86, it's a trouble-maker.  Use __dpmi_int instead.  The 
DJGPP FAQ explains the problems with int86 in section 18.1.  That section 
also sends you to the libc reference for int86, which explains more about 
this issue.

That's because BC 3.1 is a 16-bit compiler, while DJGPP is a 32-bit 
compiler.

What long filenames?  The linker works perfectly for me on plain DOS, no 
matter what names I submit to it (assuming they don't use characters that 
are invalid in DOS file names).  Please describe the specific problems 
that you have, including file names, command line, error messages, etc.
