I'm pretty sure it's libsasl2 that's the culprit, but since its DLLs are
in /usr/lib/sasl2, which is not in the PATH, I don't see how that could
work.

I might take a look at libsasl2 and see if recompiling it helps.
Unfortunately, it's orphaned and I know absolutely nothing about SASL,
so I'm loathe to adopt it.

Worse comes to worse, I'll just disable SASL support in SVN.

It's interesting, though, that this behavior just surfaced. This didn't
occur with Cygwin 1.7.1 as far as I remember, and I'm sure I had
libsasl2-devel installed at that point. There must have been some change
in cygwin1.dll that has caused this.
