Build GDB 7.0 with Cygwin -mno-cygwin option.

[Dmitry Smirnov <divis1969 at mail dot ru>]

Hi,

Is it possible to build GDB 7.0 using Cygwin (i686-pc-cygwin) but with Mingw compiler?
Usually, this requires -mno-cygwin option but I did not find this option in any file.

Should I use --build=i686-pc-mingw32 for configure? I had tried, but got the following error:
