The malloc() function is not reserved or defined by ANSI C.  In
theory, therefore, an ANSI C compiler must allow you to define a
malloc() function (perhaps even one which has nothing to do with
memory allocation), without breaking any ANSI C functions.  I guess
non-ANSI C functions could be affected, though.

In practice, on a unix machine I have supplied alternate versions of
malloc() to a program, and everything worked fine.  I haven't tried
with DJGPP, but I bet it would work fine.
