[fetchmail] Cygwin fetchmail 6.0.0 build problem due to gettext issue

[Jason Tishler]

fetchmail 6.0.0 (and 5.9.14) does not build cleanly under Cygwin:

    http://cygwin.com/ml/cygwin/2002-09/msg00901.html

and possibly other platforms where gettext is in libintl instead of
libc.

The crux of the problem seems to be that fetchmail's aclocal.m4 was
regenerated (between 5.9.13 and 5.9.14) against a version of gettext
that has a buggy "GNU gettext in libintl" check.

If I'm correct, could the next fetchmail release be built against a
version of gettext without the above problem?

Thanks,
Jason
