That line is flat-out wrong.  Delete it.  You're already in a 
--host=*cygwin* specific section of your configure.ac script, so there's 
no further precautions to be taken.

While at it, you may just as well delete the entire "with_cygwin_native" 
branch (lines 100..105), because that has been un-applicable for years. 
  Building for native windows (i.e. MinGW) is has long since stopped to 
be done by a -mno-cygwin flag.  Instead you would pass the configure 
script a --host={something with mingw in it} flag to initiate a proper 
cross-build, and that will bring you into the existing --host=*mingw* 
case abvoe.

Checking for GCC is almost certainly a red herring here.

Not really, because whatever you mean by "WND builds", they won't be 
ending up in that cygwin case.
