PATH_MAX is from Posix and does include the trailing NUL.
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
CYG_MAX_PATH as a convenient, not to short, not too long 'happy medium'.

Thou shalt *not* use CYG_MAX_PATH anymore. Use NT_MAX_PATH or
dynamic allocation instead when accessing real files. Use
MAX_PATH in case you need a convenient small buffer when creating
names for synchronization objects or named pipes. */
