Interesting. My results are from Solaris 9 and are quite verifiable:

% uname -a
SunOS xxxxx 5.9 Generic_117171-13 sun4u sparc SUNW,Ultra-5_10
% getconf -a | grep PATH_MAX
PATH_MAX: 1023
_POSIX_PATH_MAX: 255

But hang on, let me fire up my beta of Solaris 10 from a few months ago ...

% getconf -a | grep PATH_MAX
PATH_MAX: 1024
_POSIX_PATH_MAX: 255
_XOPEN_PATH_MAX: 1024

Sheesh, they're all over the map on such a basic thing! And they still
don't know that POSIX says _POSIX_PATH_MAX *must* be 256? Someone from
Sun please restore my faith!
