MAXPATHLEN is from Unix.
Thou shalt use CYG_MAX_PATH throughout. It avoids the NUL vs no-NUL
issue and is neither of the Unixy ones [so we can punt on which
one is the right one to use].
Windows ANSI calls are limited to MAX_PATH in length. Cygwin calls that
thunk through to Windows Wide calls are limited to 32K. We define
