It's bad form for one part of a program to communicate with another
part by making persistent changes to the environment of all subsequent
child processes. For example, it can cause odd bugs when building
Emacs from within Emacs (eg bug#6401, maybe).
* nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
(ns_init_paths): Do not set EMACSDATA, EMACSDOC.
* nsterm.h (ns_etc_directory): Add it.
* callproc.c [HAVE_NS]: Include nsterm.h.
(init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
($(BLD)/test-distrib.exe): Use LIB_SRC, not SRC.
(LIB_SRC, NT_INC, GNU_LIB, MS_W32_H, CONFIG_H, INTTYPES_H, NTLIB_H)
(SYSTIME_H): New macros.
(SRC): Redefine to point to src/, not current directory.
($(BLD)/ctags.$(O), $(BLD)/ebrowse.$(O), $(BLD)/emacsclient.$(O))
($(BLD)/etags.$(O), $(BLD)/hexl.$(O), $(BLD)/make-docfile.$(O))
($(BLD)/movemail.$(O), $(BLD)/ntlib.$(O), $(BLD)/pop.$(O))
($(BLD)/profile.$(O), $(BLD)/test-distrib.$(O)): Update dependencies.
($(BLD)/regex.$(O)): New dependency.
* marker.c (MARKER_DEBUG): Move marker debugging code under
#ifdef MARKER_DEBUG because byte_char_debug_check is too slow
for bootstrap with --enable-checking (~3x slowdown reported
by Juanma Barranquero <lekktu@gmail.com>).
(verify_bytepos): Move under #ifdef MARKER_DEBUG.
* configure.in (WARN_CFLAGS): Remove -Wno-deprecated-declarations.
(HAVE_LIBPNG_PNG_H): Don't bother checking for this if we have png.h.
(PNG_DEPRECATED): Define when compiling with older PNG versions.
src/ xdisp.c (display_line): Add commentary about displaying
truncation glyphs on GUI frames.
(produce_special_glyphs): Move here from term.c.
src/term.c (produce_special_glyphs): Move to xdisp.c.
src/dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
section.
* src/lread.c (load_path_check): New function, split from init_lread.
(init_lread): Reorganize. Motivation:
If EMACSLOADPATH is set, check/warn about that rather than the
defaults, which we are not going to use. Hence we can remove
the turn_off_warning and WINDOWSNT || HAVE_NS tests.
Don't warn if site-lisp directories are missing.
If not installed, start from a blank load-path, since
PATH_LOADSEARCH refers to the eventual installation directories.
src/xdisp.c (init_iterator): Get dimensions of truncation and
continuation glyphs even if on GUI frames. Adjust
it->last_visible_x on GUI frames when the left or right fringes,
or both, are absent.
(start_display, move_it_in_display_line_to): Handle the case of a
GUI frame without a fringe to display continuation or truncation
glyphs.
(insert_left_trunc_glyphs): Support GUI frames: make sure
truncation glyphs overwrite enough glyphs from the current line to
have sufficient space in pixels.
(display_line): Support truncation and continuation glyphs on GUI
frames. If some spare pixels are left on the line after inserting
the truncation glyphs, fill that space with a stretch glyph of a
suitably computed width.
src/term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
produce_glyphs, to support GUI sessions.
This works better on hosts where time_t is unsigned, and where
float-time is applied to the (negative) difference between two times.
* editfns.c (decode_time_components): Last arg is now double *,
not int *, and means to store all the result as a double, without
worrying about whether the seconds part fits in time_t.
All callers changed.
(lisp_time_argument): Remove last int * arg, as it's no longer needed.
All callers changed.
(Ffloat_time): Do not fail merely because the specified time falls
outside of time_t range.
* configure.in: (getwd): Don't check for it on unixware.
(random, rint): Don't check for these on hpux.
(res_init, libresolv): Don't check for these on darwin.
* src/s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
* src/s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
* src/s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
