[xemacs-hg @ 2002-07-23 08:34:59 by youngs] 2002-07-15 Jerry James <james@xemacs.org> * make-docfile.c: Change whitespace and organization to reduce the size of the diff against FSF Emacs sources and synch to Emacs 21.2. Remove unused DO_REALLOC. Mark XEmacs changes and additions more clearly. Reintroduce previously deleted Emacs code inside #if 0 ... #endif. * make-docfile.c (next_extra_elc): Replace goto with do-while. * make-docfile.c (main): Put XEmacs-only args in one place. * make-docfile.c (write_c_args): Change buff to buf to match Emacs. Replace pointer arithmetic with simpler array syntax. * make-docfile.c (scan_c_file): Note that DEFSIMPLE and DEFPRED no longer exist. Correct the "name too long" test (off by one). Die with message if a DEFUN has no docstring instead of hanging. * make-docfile.c (scan_lisp_file): Introduce while loops used in Emacs sources to skip consecutive blank lines. 2002-07-21 John Paul Wallington <jpw@xemacs.org> * process.el (substitute-env-vars): New function; sync with GNU Emacs 21.1.50. (setenv): Add optional arg SUBSTITUTE-ENV-VARS; sync with GNU Emacs 21.1.50. 2002-07-20 Mike Sperber <mike@xemacs.org> * eval.c (run_post_gc_hook): Use more correct flags when running post-gc-hook. 2002-07-20 Mike Sperber <mike@xemacs.org> * process-unix.c (child_setup): Don't try to close file descriptors for chid process once again---it's already being done in close_process_descs. (unix_create_process): Call begin_dont_check_for_quit to inhibit unwanted interaction (and thus breaking of X event synchronicity) in the child. 2002-07-15 Jerry James <james@xemacs.org> * lisp.h: Make Qdll_error visible globally. * symbols.c (check_sane_subr): Revert 2002-06-26 change. Check only if !initialized. * symbols.c (check_module_subr): Add parameter. Duplicate check_sane_subr checks, but signal an error instead of asserting. * symbols.c (defsubr): Use check_module_subr parameter. * symbols.c (defsubr_macro): Ditto.

This is a list of the status of XEmacs on various machines and systems.
See PROBLEMS for particular problems and possible workarounds.

Much effort has gone into making XEmacs work on as many different
machines, configurations, and compilers as possible.

Much effort has gone into making XEmacs 64-bit clean.

Much effort has gone into removing system-specific code, and replacing
such code with autodetection at configure time.

The XEmacs core should build "out of the box" on most Unix-like systems.

XEmacs 21.2 was tested and `make check' succeeded on these Unix
configurations as of 2001-02-10:

alphaev56-dec-osf4.0e (both Compaq C and gcc)
i386-unknown-freebsd4.2
i386-unknown-netbsdelf1.5
i586-sco-sysv5uw7.0.1 (both SCO's cc and gcc)
i686-pc-linux-gnu
hppa2.0-hp-hpux10.20 (both HP's ANSI cc and gcc)
mips-sgi-irix6.5 (both MIPSpro cc and gcc)
rs6000-ibm-aix4.3.0.0 (both IBM's xlc and gcc)
sparc-sun-solaris2.6 (both Sun's Forte C and gcc)
sparc-sun-solaris2.7 (both Sun's Forte C and gcc)
sparc-sun-sunos4.1.4 (gcc)

Some systems have a dual mode 32-bit/64-bit compiler.  On most of
these, XEmacs requires the --pdump configure option to build
correctly with the 64-bit version of the compiler.

mips-sgi-irix6.5, CC="gcc -mabi=64"
mips-sgi-irix6.5, CC="cc -64"
rs6000-ibm-aix4.3.0.0, CC="cc -q64"

On most of these systems, XEmacs also builds with a C++ compiler,
but not "out of the box".  This feature is only for use by the
maintainers.

XEmacs 21.2 is known _not_ to work on any machines with m680x0
processors.  Sorry, all you sun3 and Unix PC nostalgia buffs out there.

VMS has never been supported by XEmacs.  In fact, all the old VMS code
inherited from Emacs has been removed.  Sorry, all you VMS fans out there.
