The FSERROR define is on all the time now. It was not controlling
all of the functionality, with many places setting Lisp_errnno
outside of the code controlled by the define.
The `open()` call can take a third argument (for when the mode
is `O_CREAT`). However, it is not needed here as we aren't
using `O_CREAT`. (And if we needed an extra arg, it wouldn't
have been `NULL`.)
* FD_ISSET requires that the fd being tested is >= 0, so unset fd -1 causes trouble.
* Remove code to enable X I/O signal generation from xinit.c
If the I/O signals are enabled before the signal handler has
been set up, the default action on receipt of a SIGPOLL or SIGIO
will be that the program exits. For now, turn the signals off,
as they aren't necessary and may not even be an improvement.
* Ensure fds are declared as signed and initialized (to -1)
The global fds may be accessed from the signal handler before any
particular device has been opened. Ensure that the fds are initialized
statically and that the value is distinguishable from all valid descriptors.

This wasn't enabled and the corresponding code wouldn't have
compiled. The `utime()` function is also deprecated in POSIX.
This used to be enabled for HPUX and RISCOS.
When things were renamed for DOS, `asmbitblt.c` became `asmbbt.c`,
but the old file got left around. It was never converted fully
from K&R prototypes, but apart from that, is the same as `asmbbt.c`.
I_SETSIG is part of the STREAMS interface, which is only present
on Solaris (among our supported platforms), so simplify this check.
Other usages of I_SETSIG could be improved, but they need more
investigation and perhaps removal.
We don't want to modify emulation code yet as ISC support included
a number of other things, including some i386 code that isn't used
on other platforms, but is still useful as a reference.
This also removes support for the DEC3100 keyboard, but leaves a
constant behind for it as I'm not sure about re-numbering.
[NBriggs: keyboard type numbers are stored within all sysouts. Do not renumber supported keyboards, do not reuse previously used keyboard numbers]
This removes code related to HP9000, HPTIMERBUG, and HPUX defines.
It leaves KB_HP9000 for now as I'm not sure about renumbering
those constants.
This should not impact any of the core emulation code.
This platform had no emulation-related changes.
Remove code for IRIX40, INDIGO definitions.
In disk code, simplify a chain of #ifdef's around fsync handling.
