* Check.h, Stipple.h, XCursors.h, XWaitCur.h, Xcursdef.h,
Xdefcur.h, and Xicon.h were combined into xbitmaps.h.
* Xdisplay.h is not used and the contents are in MyWindow.h, which
is used.
* XVersion.h and Xdeflt.h became xdefs.h. Remove 2 stragglers
that were still including XVersion.h.
`timer.c` uses `F_SETSIG` which is a GNU extension. As such, it
needs `_GNU_SOURCE` to be defined, but this was only done for
x86_64, not the other Linux platforms that we have build system
support for.
Closesinterlisp/medley#97.
* Move clang/gcc options into makefile-header.
This puts all of the shared options into a single place so that
we can easily update it.
* Add -fwrapv to the clang/gcc command lines.
This is a step along the way to fixing interlisp/medley#90.
Enabling `-fwrapv` will let overflow checks that rely upon undefined
behavior to work correctly. Without this, with modern versions of
clang and gcc, the overflow checks in the C code are eliminated
by the compiler, resulting in incorrect behavior on the part of
Maiko.
See the linked bug for details and discussion.
Hopefully, this usage of `-fwrapv` will go away once we're using
the correct compiler builtins to detect and handle overflow
correctly.
CLX is a Common Lisp implementation of the X client library.
It has some code in C, which was present here as `src/socket.c`
and `src/socdvr.c`, exposed via opcodes in `src/subr.c`. This code
had been removed (with prejudice apparently) by commenting out
the code in `src/subr.c` with `#if NEVER`.
This code would've been used by the Medley system images, but
that code doesn't appear to be present. (There may or may not
be something related in `XMAS` in the Medley repository.)
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.
On SunOS4, we build `xc.c` by jumping through a lot of hoops to
perform a particular set of operations. We don't do that on other
platforms and this will help clean up the Linux and FreeBSD makefiles.
These directives were already not present in the macOS makefiles.
This is an internal macro to GNU libc and wasn't meant to be
defined like this. Well, it was. It was deprecated and removed
some years ago, so it isn't doing anything at all here now.
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.
These were binaries built for SPARC to test some assembler
optimizations.
They aren't needed as part of the version control as they're just
artifacts of the past.
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.
Ultrix hasn't seen an update since 1995 and the DEC3100 hardware
that this was originally written for was released in 1989.
It isn't likely that anyone has Ultrix running on hardware where
they would also want to run this.
This was replaced by medleyfp.h. Perhaps this happened because
some systems have an fp.h in their system includes and the naming
collision was an issue. But nothing uses fp.h and medleyfp.h is
an updated version of the contents.
This also updates a bunch of manually managed dependency lists
to reflect the usage of medleyfp.h rather than fp.h.
Nick Briggs: Note that on OSF1 medleyfp.h includes the system fp.h (probably the origin of the renaming)
The config.guess script returns "aarch64-apple-darwin20.1.0" for an M1 Big Sur mac mini.

* Docker compatibility: makefile and headers
- _GNU_SOURCE required for F_SETSIG
* Remove duplicate makeright.sh script
* Update some includes that don't exist on modern Linux (termio.h); Clang in Docker
has trouble resolving them automatically
Be clear that the code is not clean for pointer aliasing.
