Hi Art,
Spend some time to study how to work with make files. With cygwin, gnu make
is a viable option.
Make will only recompile files that have changed since a previous
compilation.
gnu make also understands file extensions and what the next logical step
will be. for instance, 'make x.o' will effectively do GCC -c x.c, if x.c is
in the current working directory.
