If you have the latest version of Borland's make (V3.0) you can use the make &&
operator and a response file as follows:

$(EFILE):  $(OBJS)
    tcc  -c -m$(MM)  @&&!
$(OBJS)
!

The "@" tells tcc to read the next argument(s) from the given file. The "&&!"
tells make to put everything (starting with the next line) in a temporary file
until it hits the next "!". It then substitutes the filename after the "@" on
the command line and executes the line. I have used this technique to get
around the 127 character limit. And, yes, the "$(OBJJS)" macro is expanded.
