The problem is that it looks like perl is calling getcwd like this:

getcwd (NULL, 0);

and cygwin is returning a NULL, as is mandated by both the Single Unix
Specification and the linux man page.  1.1.4 allowed zero length length
arguments but that was a bug that I fixed in 1.1.5.

I had no idea that people were relying on the bug.

I'm not sure what to do about this.  I am loathe to accomodate a bug
like this but I don't want to force a new perl release or endure to the
next two years of "I cygwined my perl 1.1.[5-9] and it am broke" messages
either.
