the current alpha version of the GNU coreutils (5.0.90) contains this

"chown: `.' is no longer recognized as a separator in the OWNER:GROUP
 specifier on POSIX 1003.1-2001 systems.  If chown *was not* compiled
 on such a system, then it still accepts `.', by default.  If chown
 was compiled on a POSIX 1003.1-2001 system, then you may enable the
 old behavior by setting _POSIX2_VERSION=199209 in your environment."

The gLSB currently states:

"chown is as specified in the Single UNIX Specification but with
 differences as listed below."
"The use of the '.' character as a separator between the specification of
 the user name and group name is supported (in addition to the use of the
 ':' character as specified in the Single UNIX Specification)."

Since the default chown tool under Linux now favours the ':' it makes
sense to move this the '.' sentence into the "LSB Deprecated Differences".


PS: This is also known as bug
    [ 783357 ] chown utility: _POSIX2_VERSION
