Subject: [PATCH] fnmatch: add bare minimum support for character equivalents

Hi,

fnmatch() parses character equivalents like [[=e=]] but it doesn't
attempt to match them. I think it's common to not handle character
equivalents properly, but I think that most implementations at
least treat "[[=e=]]" as though it were just "e". This (six line)
patch does that.

Collating sequences (e.g. [[.ch.]]) are also parsed but not handled.
This patch does nothing about that.

cheers,
raf
