If gcc produces protected mode code, is there a similar program, under GNU,
that
will produce real-mode programs. I bet that the majority of the code that
people on this news group/mailing list write do not NEED a protected mode
compiler. It's fine if you intend to write a program that will take over
the system,
but it's not necessary if you just want to write a small utility, its
pointless.
All protected mode compilers dont produce baisc files that size do they?
