It's not just Gateway.  We have a Mylex MXA386 motherboard on a
machine here...  enquire locks up the machine entirely, and does a
partial processor and bus reset.

This was confirmed to me from a couple of other users with Mylex
boards with different OS's.  It's definately Mylex's fault in this
case.  (oh yeah, it only happens when the 387 coprocessor is used for
enquire. The system survives if the 387 is present on the motherboard,
but not configured into the OS (but it's _much_ slower))

The interesting thing is that  gcc-2.2.2 generated code for exquire
that worked before.  Now, with 2.3.3 and 2.4.5, it locks up good!
