You should ask Windows questions on the [EMAIL PROTECTED] mailing list;
there are more Windows-knowledgeable folks there.

You will have to change the rule that you use to detect this situation
and remove the file for you. If you were using a UNIX shell I'd suggest
something like this:
%.o : %.c
@echo $(COMPILE.c) -o $@ -c $<; \
$(COMPILE.c) -o $@ -c $< && exit 0; \
r=$$?; \
rm -f $@; \
exit $$r
If you don't have a UNIX shell you'll have to figure it out yourself.

There is no way to create a file from within a makefile, except as part
of a target command script:
foo:
echo first line > $@
echo second line >> $@
echo third line >> $@
etc. Or, you could try using the $(shell ...) function but you'd
probably run into command line length limitations there as well.
