I think that the easiest way is to redefine the rule to compile that file.
To find the command to execute for compiling, inspect the Makefile.in
that automake has created for you.

I guess the following should work:

re.$(OBJEXT): this.h that.h
re.o: re.C
        $(CXXCOMPILE) -O3 -c -o $@ $<
re.obj: re.C
        $(CXXCOMPILE) -O3 -c -o $@ `$(CYGPATH_W) '$<'`

HTH,
