Having encountered this problem about a month ago here's my $0.02.

Gateway shipped some mother boards that will lock up during floating
point operations. The mother boards in question are "Rev E". You can
call Gateway and they will replace you broken mother board free
of charge regardless of when you bought the machine, service contract
and/or warranty.

From the Info file:
   * On some 386 systems, building the compiler never finishes because
     `enquire' hangs due to a hardware problem in the motherboard--it
     reports floating point exceptions to the kernel incorrectly.  You
     can install GNU CC except for `float.h' by patching out the
     command to run `enquire'.  You may also be able to fix the problem
     for real by getting a replacement motherboard.  This problem was
     observed in Revision E of the Micronics motherboard, and is fixed
     in Revision F.  It has also been observed in the MYLEX MXA-33
     motherboard.
