trouble with ( in path or target name with CVS gmake on cygwin

I did a CVS checkout of gmake on this date:

checkout date: 2009-12-30 16:00
$ cat CVS/Root
:pserver:[email protected]:/sources/make
$ cat CVS/Repository
make

I have the cygwin built make renamed to make.orig:

$ make.orig --version
GNU Make 3.81

$ make --version
GNU Make 3.81.90

I create some small makefiles, one with () in the file name:


$ cat "foo.make"
include bar(x).make

$ cat "bar(x).make"
foo(x)/tada:
         @echo tada

Works with original make:

$ make.orig -f "bar(x).make" "foo(x)/tada"
tada

Fails with cvs make:
$ make -f "bar(x).make" "foo(x)/tada"
make: *** No rule to make target `foo(x)/tada'.  Stop.

Works with original make:
$ make.orig -f "foo.make"
tada

Fails with CVS make:
$ make -f "foo.make"
foo.make:1: x).make): No such file or directory
make: *** No rule to make target `x).make)'.  Stop.
