I am not at all a mingw developer and I personally agree.
However, just my 2p:

For all windows targets, regardless if 32 or 64 bit, GCC
defines WIN32 = 1 implicitly. In case of 64 bit, _WIN64 is
defined additionally.  Maybe this was a motivation.

BTW: This is not the only confusing thing. There is amd64
used for intel as well ...
