In the [link|http://cygwin.com/faq/faq.html|Cygwin FAQ]:

\r\n\r\n
\r\nAfter a new installation in the default location, your mount points will look something like this:\r\n
\r\n
\r\nbash$ mount\r\nC:\\cygwin\\bin on /usr/bin type system (binmode)\r\nC:\\cygwin\\lib on /usr/lib type system (binmode)\r\nC:\\cygwin on / type system \r\n
\r\n
\r\n\r\n

I also found a nifty solution to creating links for shares. The mountpoint limit is hardcoded to 30 (see FAQ), so links tend to be more flexible & useful.
