This should have been handled by 0.9.3 out of the box, except that the
case in configure only checked for mingw and pw32, not cygwin.  I've
just added cygwin, but I'm totally not sure if that's the right thing to
do as it may not work for a "true" cygwin build - your hybrid approach
is rather non-standard I suspect.

Incidentally, if you do need to specify extra libs for PHP, then
PHP_LIBS is a better option that xapian_la_LDFLAGS.

The original bug was really fixed.  Debian unstable had PHP built with
ZTS enabled for a while, but reverted to non-ZTS.  But during that
period, the Xapian PHP bindings weren't building on my debian unstable
box.  With the patch applied they did build.

But this seems to be another instance of the same class of problem,
presumably in some SWIG code added since then.

Is SWIG CVS HEAD any better?
