previous occurrences of MAXPATHLEN and FILENAME_MAX have been changed
to use MaxPathSize instead.
If MAXPATHLEN is not defined, then assume a default value of 1024
(this is primarily for use on the Hurd).
The reason for this is that some older platforms define FILENAME_MAX
to be 14, although MAXPATHLEN is 1024. On BSD-derived systems,
FILENAME_MAX And MAXPATHLEN are both 1024.
Bump pkg_install version to 20041226.
These modifications have been tested so far on a NetBSD-current bulk
build.
