I'm compiling a simple stdio-only program on a NeXT box. One of the
modules of the program is my own version of malloc(), free(), and
realloc().

When I go to link my program, I get errors from the linker claiming
that malloc() is redefined. If I don't link in my own version of
malloc(), it links fine, albeit without the code I want.

The NeXT OS is the first system I've gotten these errors - most OSs
will use my malloc() and never link in the standard malloc(). From
what I've read of the ld man page, it should work the way I want it
to. I'm guessing the problem is general - how do I override standard
library routines in C code? I'd prefer email responses.

cc -o main main.o malloc.o
