I think it's clear that users of the 32-bit PC architecture are expected
to sacrifice some performance by their choice.  Why cannot the question
whether the tradeoffs are acceptable be reserved to those users?  The
mere existence of the USE_WIDE_INT MinGW configuration is evidence
enough that users exist who do not need our arbitrary judgement.
