You can see output there:
_PC_FILESIZEBITS - 3rd column
_PC_LINK_MAX - 4th column
_PC_NAME_MAX - 5th column
_PC_PATH_MAX - 6th column
Solaris Nevada ZFS 64 -1 255 1024
UFS 41 32767 255 1024
FAT 33 1 8 1024
NFS 41 32767 255 1024
Solaris 8 UFS 41 32767 255 1024
NFS 40 32767 255 1024
Centos4(2.6.11) EXT3 64 32000 255 4096
XFS 64 2147483647 255 4096
Mac OSX leopard HFS+ 64 32767 255 1024
cygwin 1.5 on NTFS. But 1.7 will a have much larger _PC_PATH_MAX.
_PC_FILESIZEBITS undefined
_PC_LINK_MAX = 8
_PC_NAME_MAX = 260
_PC_PATH_MAX = 257
So this is really bad.
