Hi,

currently I try to compile cygwin-1.7.0-50.=20

The make fails with the following error:

----------------

----------------


Hint: Before I started configure I had to manually create a directory
"i686-pc-mingw32" in the usr directory. Without this configure failed.

I use the current version of cygwin release 2.

Best regards
  Martin
