Does anyone have a hacked up version of make that automatically generates a
response file without any modification to the makefile?  That is, interpret:

target:
	$(CC) ....lots of stuff here requiring response file....

as
target:
	$(CC) @target.rsp

where the file target.rsp is automatically generated by the make program.  It
would also be nice if files with .o extension were expanded to a .obj
extension.   I know much of this could be done with macros but I would like to
take a generic Unix Makefile and have the make program quietly but
intelligently `dosify' it.
