[distcc] mmap problems on cygwin?

[Daniel Kegel]

I just build distcc-2.13 on Cygwin, and am playing around a bit...
and noticed the following error from the server:

distccd[7580] (dcc_r_bulk_plain) mmap output fd6 failed: No such device or address

(It'd be helpful if that error message had a filename associated with it.)

Here's more of the log.  I'm tracking down some other problems of
my own making, so I'm not stuck on this, just posting this in case
it raises any red flags for the maintainers...
