------ gc-in-window-procedure fixes ------
alloc.c: Create "post-gc actions", to avoid those dreaded "GC during window
procedure" problems.
event-msw.c: Abort, clean and simple, when GC in window procedure. We want
to flush these puppies out.
glyphs-msw.c: Use a post-gc action when destroying subwindows.
lisp.h: Declare register_post_gc_action().
scrollbar-msw.c: Use a post-gc action when unshowing scrollbar windows, if in gc.
redisplay.c: Add comment about the utter evilness of what's going down here.
------ cygwin setitimer fixes ------
Makefile.in.in: Compile profile.c only when HAVE_SETITIMER.
nt.c: Style fixes.
nt.c: Move setitimer() emulation to win32.c, because Cygwin needs it too.
profile.c: Make sure we don't compile if no setitimer(). Use qxe_setitimer()
instead of just plain setitimer().
signal.c: Define qxe_setitimer() as an encapsulation around setitimer() --
call setitimer() directly unless Cygwin or MS Win, in which case
we use our simulated version in win32.c.
systime.h: Prototype mswindows_setitimer() and qxe_setitimer(). Long
comment about "qxe" and the policy regarding encapsulation.
win32.c: Move setitimer() emulation here, so Cygwin can use it.
Rename a couple of functions and variables to be longer and more
descriptive. In setitimer_helper_proc(), send the signal
using either mswindows_raise() or (on Cygwin) kill(). If for
some reason we are still getting lockups, we'll change the kill()
to directly invoke the signal handlers.
------ windows shell fixes ------
callproc.c, ntproc.c: Comments about how these two files must die.
callproc.c: On MS Windows, init shell-file-name from SHELL, then COMSPEC,
not just COMSPEC. (more correct and closer to FSF.) Don't
force a value for SHELL into the environment. (Comments added
to explain why not.)
nt.c: Don't shove a fabricated SHELL into the environment. See above.
------ misc fixes ------
glyphs-shared.c: Style correction.
xemacs-faq.texi: Merge in the rest of Hrvoje's Windows FAQ. Redo section 7
to update current reality and add condensed versions of
new changes for 21.1 and 21.4. (Not quite done for 21.4.)
Lots more Windows updates.
process.el: Need to quote a null
argument, too. From Dan Holmsand.
startup.el:
startup.el: Call MS Windows init function.
win32-native.el: Correct comments at top. Correctly handle passing arguments
to Cygwin programs and to bash. Fix quoting of zero-length
arguments (from Dan Holmsand). Set shell-command-switch based
on shell-file-name, which in turn comes from env var SHELL.
