AC_PKG_MICO patch

[jfasch]

I found that AC_PKG_MICO does not work in every case. There were two
problems which I fixed in confix.sf.net's vendor import of the
archive. I append a patch below.

1. configure.in:1309: /usr/bin/m4: Bad regular expression `[[[\([[[[]]]]\)]]]': 
Unmatched ) or \)

   I'm not really sure what's happening, but the first region of the
   patch definitely solves this (in a brute force approach
   however). (Note that quoting the AC_MSG_ERROR argument with current
   quotes (changequote(<<, >>) happened before) does not help.)

2. checking mico dependencies... tr: invalid backslash escape `\"'

   This happens when I use bash and POSIXLY_CORRECT is set to 1, and
   is solved by the second region of the patch. I tested `tr '"' 'x'`
   (without escaping '"') under bash (Linux), and SunOS 5.9, HP-UX
   10.20, and AIX 5.2 Bourne shell. Other I don't have access to.
