  BUG#27141 - Calling tell(-1) under Windows causes assertion failure in Debug mode
  
  Original problem was by Magnus (see BUG25807).
  
  Currently only windows debug build causes assertion failure. This patch assures
  that my_tell gets correct file descriptor on any platform by DBUG_ASSERT macro.

    Added assertion in case my_tell gets wrong file descriptor.

# This is a BitKeeper patch.  What follows are the unified diffs for the
# set of deltas contained in the patch.  The rest of the patch, the part
# that BitKeeper cares about, is below these diffs.
