[patch testsuite]: Fix some mingw testcases in gcc.dg

[Kai Tietz]

Hello,

this patch fixes some regressions introduced by default-option
-fms-extensions for mingw-targets.

ChangeLog

2014-03-17  Kai Tietz  <ktietz@redhat.com>

    * anon-struct-1.c: Add -fno-ms-extensions option for mingw targets.
    * anon-struct-11.c: Likewise.
    * anon-struct-2.c: Likewise.
    * c11-anon-struct-2.c: Likewise.
    * c11-anon-struct-3.c: Likewise.

Tested for i686-w64-mingw32, and x86_64-unknown-linux-gnu.  Ok for apply?

Regards,
Kai
