If you are using GNUish make, put this line in your makefile:

LONGARGS = gcc

The LONGARGS variable is a list of programs that understand the GNUish
environment variable convention of passing long command lines.  All
go32 programs do, as of 1.08 (or was it 1.07?).  If you are making a
library or removing lots of files, you may want to set LONGARGS to
something like:

LONGARGS = gcc:ar:rm

The "old" way of putting link specifications into a separate file will
still work, assuming you have a convenient way of creating the
separate file.  But that is not necessary given the above method.
