-On some 386 systems, building the compiler never finishes because
-@code{enquire} hangs due to a hardware problem in the motherboard---it

-getting a replacement motherboard.  This problem was observed in
-Revision E of the Micronics motherboard, and is fixed in Revision F.

-If you encounter this problem, you may also want to consider removing

-On some 386 systems, GCC crashes trying to compile @file{enquire.c}.
-This happens on machines that don't have a 387 FPU chip.  On 386
-machines, the system kernel is supposed to emulate the 387 when you
-don't have one.  The crash is due to a bug in the emulator.

-One of these systems is the Unix from Interactive Systems: 386/ix.
-On this system, an alternate emulator is provided, and it does work.
-To use it, execute this command as super-user:

-ln /etc/emulator.rel1 /etc/emulator

-and then reboot the system.  (The default emulator file remains present

-Try using @file{/etc/emulator.att}, if you have such a problem on the

-Some versions of the Pyramid C compiler are reported to be unable to
