PATH_MAX is from Posix and does *not* include the trailing NUL.

MAXPATHLEN is from Unix.

Thou shalt use CYG_MAX_PATH throughout. It avoids the NUL vs no-NUL

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'.
