Well, there certainly appears to be!  If I choose gcc it defaults to
mingw32 as it appears to the end user.  And looking a profile.xml
doesn't give me any hint as to how mingw32 is the default by
appearance.

But currently it defaults to mingw32 as it appears to the user.  How
is that determined?

Well, then let us discuss end user experience as it relates to
installing software where MinGW.org is providing both 32bit and 64bit
versions of software.  Surely if the user is using a 64bit version of
mingw-get he'll want it to appear to default to mingw64 instead of
mingw32.
