[xemacs-hg @ 2001-05-25 11:26:50 by ben] device-msw.c, eldap.c, emodules.c, hpplay.c, process-unix.c, sound.h, tooltalk.c, win32.c: Revert Martin's attempted compile-warnings fix. It does fix the warnings, but not the right way. We are trying to eliminate the raw use of `char' and `unsigned char' absolutely everywhere. There is never an occasion to reintroduce these. buffer.h: Instead, we fix these macros so they don't care about the type of their lvalues. We already do this for the non-C-string equivalents of these, and it's correct because it should be OK to pass in an SBufbyte *, for example. In any case, we do not need any type-correctness checking here -- errors will be caught for sure as soon as we remove the -Wno-sign-compare switch. mule-charset.c: Use invalid_argument, not generic signal_error (Qerror, ). alloc.c, chartab.c, console-gtk.c, console-msw.c, console-stream.c, console-stream.h, console-tty.c, console-tty.h, console-x.c, console.c, console.h, device-x.c, device.c, elhash.c, eval.c, faces.c, faces.h, fns.c, glyphs.c, glyphs.h, gui.c, gui.h, lisp.h, lread.c, nt.c, objects-gtk.c, objects-gtk.h, objects-msw.c, objects-tty.c, objects-x.c, objects.c, process-unix.c, rangetab.c, search.c, specifier.c, toolbar.c, window.c, window.h: Rename Error_behavior to Error_Behavior, to be consistent with general naming practices (Lisp_Object, Char_Binary, etc.).
