Subject: [PATCH] Provide replacement value for PATH_MAX on platforms without
 it.

The buffer length is used in a static array returned from
Extra_FileNameGenericAppend(), used many places in the code, and a
more dynamic approach would require a huge refactoring.  There is no
guarantee that the 4096 value picked is large enough, but it matches
common values found on Linux.
