[ts-gen] compile problems on cygwin

The tarball at the perma-link:
    ftp://ftp.trading-shim.org/pub/local/trading-shim/attic/shim-080411.tgz
is exposing a Cygwin macro definition failure to #undef, 
with the test which Bill outlines herein.  I provide a copy 
to the Cygwin reporting address.

Yup -- I have replicated it locally, when I hit Bill's email. 
I get (in ./src. on an unpacked tarball):

$ g++ rph_test.c
In file included from glossary.h:48,
                  from rph-test.c:1:
functional.h:213: error: expected init-declarator before '&' token
functional.h:213: error: expected `,' or `;' before '&' token
$

This on a Win 2000 box fully updated as of this afternoon, 
against the Cygwin distribution mirrors.

And so something in the Cygwin macro def's is not 
#undef'ing after itself.    I assume the Cygwin folks know how 
they want a bug report and to track this down?

I'll file it in their bug tracker, and track it with them, if 
you'll provide a pointer, Gabriel.

I am used to seeing Corinna Vinschen <vinschen at redhat.com> 
post update release notices on the cygwin-announcement mailing 
list. In his announcements, he requests reports to:
     cygwin at cygwin.com
So I have sought to subscribe there, and file this there, per 
the request of those announcemnts.
