Problem at step 1.

however the same command seems to function if I eliminate the -W
-Wall -ansi -pedantic -gstabs+ default flags by using *gcc.  What
do I really need?  Obviously the only portion that needs profiling
is the malloc.c content, and that should be as detailed as
possible. Should I be using gstabs+, gstabs, or g?  The other
modules are compiled with the defaults above.  Does that matter?

I assume that if malloc is linked before the library search the
library version will be omitted?

All doubtless 2nd nature to you, but not to me.  Hand holding
needed :-)
