Interesting as the problem changed when I added the malloc_debug(x)
function call in make.c. The test was to delete all the *.o and make.exe
before running make. The exe with the malloc_debug(x) took considerably
longer to start to do anything and as the value moved from 1 to 4 the longer
it took. The results were, I sprinkled malloc_verify() in a number of
functions in job.c with malloc_debug(4) , but  there was no new lines or
info in the output from make.

Any other ideas or hunches or clues? I have
