Replying to the list in case there are others who might be interested.
Please note how involved this gets with even a trival example. If you
can follow Paul's advice, your life will be much simpler.
You may find 4 files attached which constitute a working example of how
to deal with source files which have spaces. Note that only the source
files have spaces, as soon as I generate the object files, I no longer
have to deal with the whitespace. This causes the resultant object
files to have somewhat unseemly names.

$(shell \
for each in *.c; \
do \
echo $$each | sed -e 's, ,__whitespace__,g'; \

gcc -o $@ $(^)
.PHONY: clean
clean:
rm -f $(objects) main

reconstitute = $(subst __whitespace__,\ ,$(1))
shell-escape = $(subst $(space),\ ,$(1))
