This final cset is to fix a syntax problem in ha_myisammrg.cc where a / was left out of a format string.
It also adds a check in has_path to avoid a possible redundant comparison.

ha_myisammrg.cc:
  Replaced missing / in format string
my_getwd.c:
  Added test to see if FN_LIBCHAR != '/' before doing comparison to avoid redundant comparison

This cset is to roll out the cset applied earlier from Ingo.
This bug has been fixed with a different cset.

This is a replacement for the original patch given by Ingo.  This one comes
from Monty.
The problem is that merge files now use unix style pathnames on all 
platforms.  The merge file open code was not properly converting those
pathnames back to non-unix when necessary.

The problem was that on Windows the access method indicates that access to file 
such as "com1" and "lpt1" is allowed (since they are device names) and
this causes mysql to attempt to open them as databases or tables.

The fix was to write our own my_access method that uses other Win32 functions
to determine if the given argument is indeed a file and has to requested
mode.

This patch was submitted by Ingo and it appears to work correctly.

sql_udf.cc:
  changed dl_name to udf->dl in mysql_create_function

After review version.
Added a condition for MERGE tables. These do not have unique
indexes. But every key could be a unique key on the underlying
MyISAM table. So get the maximum key length for MERGE tables
instead of the maximum unique key length. This is used for
buffer allocation in write_record().
