MinGW issues

+ +

GCC on Microsoft Windows can now be configured via +--enable-mingw-wildcard or --disable-mingw-wildcard +to force a specific behavior for GCC itself with regards to supporting or +not the wildcard character. Prior versions of GCC would follow the +configuration of MinGW runtime. This behavior can still be obtained by not +using the above options or by using +--enable-mingw-wildcard=platform.
