I'll start checking that, but thought I'd at least give a first round of
replies.

This was with bleeding edge autoconf.git, but as part of downgrading to
automake 1.10.2, I'll also drop back to autoconf 2.63.

Haven't tested other systems yet. This was on cygwin 1.7 (still in beta), so
it could very well be a cygwin problem, although I am pretty sure that I have
also seen it on the latest stable cygwin 1.5.x. I'll confirm.

perl 5.10.0, as shipped pre-built for cygwin (same perl for both cygwin 1.5 and
1.7).

NTFS.

Indeed it is possible that some of the cygwin 1.7 improvements might be the
cause of XFile::lock behaving differently; if there is a way to trim this down
to a smaller test case, the cygwin developers would likely be able to
investigate it.
