What issues?  AFAICT compiling the original source with NDEBUG
results in a module ready for inclusion in the main library.  I
added the following readme to the distribution, not sure just now
if it is in the version on my site.  The nmalloc code has not been
altered.

---- readme quoted ----
[1] c:\c\malloc>type readme.txt
This is intended to be prepared via the makefile.

To create a testable debug version, enter "make tnmalloc".

To create an object module for use in actual systems, enter "make
malloc.o".  This will have the normal names, malloc, free,
realloc.

To create a version for profiling, enter "make tmallocp".  The
module
mallocp.o created is generally suitable for profiling, and has the
usual
names.

To create a cross-reference, enter "make xrf" (under DOS boxes
only)

The various compile time flags are set up appropriately.  In
particular
malloc.o should be immediately ready for inclusion in a library. 
It may be
desirable to "strip" debugging information from the module.

"make all" creates everything, "make clean" wipes them out.

The little test 'evilalgo' can be linked to either the stock
malloc system,
or to the malloc.o generated above.  Then time execution for an
argument of
200000.  The original library will probably fail where nmalloc
will
succeed, and nmalloc will do it a lot faster.
