MinGW 64 provides both 32 and 64 bit build tools.
I have used it for both 32 and 64 bit binaries since 5.0.1. 

and 32 bit executable also does not use emulation.


The pipe on  wgnuplot is also currently supported on MSVC.

See ChangeLog of 5.2-rc4

    * config/mingw/Makefile config/msvc/Makefile:  Mingw-w64 and MSVC have
    working popen/pclose implementations for GUI applications.  So we use
    them instead of our own "fake" pipe emulation.
    Bug #1950
