[xemacs-hg @ 2005-01-24 23:33:30 by ben] get working with VC7 config.inc.samp: Declare OPTIONAL_LIBRARY_DIR as root of library directories. Redo all graphics library defaults to mirror the versions and directories in the current binary aux distribution on xemacs web site. Enable TIFF and COMPFACE by default since you can now compile with them and binary libs are provided. xemacs.mak: Put our own directories first in case of conflict (e.g. config.h in compface). xemacs.mak: Use MSVCRT to avoid link problems. s/windowsnt.h: bytecode.c, print.c: Add casts to avoid warning. compiler.h: Add MSC_VERSION and include definitions of DOESNT_RETURN and friends here, like for GCC. Need different definitions for VC7 and VC6. s/windowsnt.h: Remove stuff moved to compiler.h. Disable warning 4646 ("function declared with __declspec(noreturn) has non-void return type") on VC7 since lots of Lisp primitives trigger this and there is no easy way to kludge around the warning. glyphs-eimage.c: Some really nasty hacks to allow TIFF and JPEG to both be compiled. #### The better solution is to move the TIFF and JPEG code to different files. glyphs-msw.c: Define __STDC__ to avoid problems with compface.h. intl-auto-encap-win32.c, intl-auto-encap-win32.h, intl-encap-win32.c, syswindows.h: Those wankers at Microsoft cannot leave well enough alone. Various functions change parameter types semi-randomly between VC6 and VC7, so we need to include our own versions that can handle both kinds with appropriate casting. EmacsFrame.c, EmacsShell-sub.c, EmacsShell.c, alloc.c, alloca.c, buffer.c, bytecode.c, charset.h, chartab.c, cm.c, console-stream.c, console.c, data.c, debug.h, device-msw.c, device-tty.c, device-x.c, doprnt.c, dumper.c, dynarr.c, elhash.c, emacs.c, eval.c, event-Xt.c, event-gtk.c, event-msw.c, event-stream.c, events.c, extents.c, faces.c, file-coding.c, fileio.c, fns.c, font-lock.c, frame-gtk.c, frame-x.c, frame.c, free-hook.c, gccache-gtk.c, glyphs-eimage.c, glyphs-gtk.c, glyphs-msw.c, glyphs-x.c, glyphs.c, gtk-glue.c, gutter.c, input-method-xlib.c, insdel.c, intl-win32.c, keymap.c, lisp.h, lread.c, lstream.c, macros.c, malloc.c, menubar-gtk.c, menubar-msw.c, menubar-x.c, mule-coding.c, native-gtk-toolbar.c, number.c, objects-msw.c, objects.c, print.c, process-nt.c, process-unix.c, process.c, ralloc.c, rangetab.c, redisplay-gtk.c, redisplay-msw.c, redisplay-output.c, redisplay-tty.c, redisplay-x.c, redisplay.c, regex.c, scrollbar-gtk.c, scrollbar-x.c, search.c, select-x.c, signal.c, specifier.c, specifier.h, strftime.c, sunplay.c, symbols.c, sysdep.c, sysproc.h, text.c, text.h, toolbar-common.c, toolbar-msw.c, toolbar.c, ui-gtk.c, unexnt.c, unicode.c, win32.c, window.c, xgccache.c, s/windowsnt.h: abort() -> ABORT(). Eliminate preprocessor games with abort() since it creates huge problems in VC7, solvable only by including massive amounts of files in every compile (and not worth it).
