The MinGW packaging guidelines at https://fedoraproject.org/wiki/Packaging:MinGW have a banner containing this text:
These guidelines are active as of Fedora 17. For older Fedora releases (including RHEL-6 and older) the old guidelines still apply which can be be found here: https://fedoraproject.org/wiki/Packaging:MinGW_Old

This banner is outdated. As Fedora 17 is EOL these guidelines are now effective for all current Fedora releases.

On RHEL-6 the situation has changed recently. In the past Red Hat maintained various mingw32 packages (based on the old mingw.org toolchain), but they were removed from the distribution as of RHEL 6.6 (as can be read at https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/6.6_Technical_Notes/index.html#deprecated_functionality). Therefore we (the Fedora MinGW SIG) decided to import the new mingw-w64 based toolchain in EPEL6. This includes the new RPM macros mentioned at https://fedoraproject.org/wiki/Packaging:MinGW and support for cross-compiling win64 binaries. Simply said: the MinGW packaging guidelines which were active for Fedora are as of now also valid for EPEL6.

Could you please remove the banner from https://fedoraproject.org/wiki/Packaging:MinGW and remove the old MinGW packaging guidelines from https://fedoraproject.org/wiki/Packaging:MinGW_Old ?
