--- Comment #1 from Umesh Kalappa <umesh.kalappa0 at gmail dot com> ---
after our investigation we found that the below change ,makes code to be
generated like identical to linux host .

This change would affect the value of macros defined in auto-build.h which is
used when building the toolchain for Windows, the different value of macros
result the different code in generated file insn-conditions.md, insn-recog.c
etc which eventually makes a different compiler is built for Windows.
Before we conclude with our changes ,we would like to hear from the experts
here on the difference behaviour(b/w hosts) and the fix .
