Message : * automake.in (handle_lib_objects_cond): Prefer `$1' over `\1'. Minor rewrite for clarity. (check_canonical_spelling): Prefer `$1' over `\1'. * depend2.am (@OBJ@): Renamed. Use @SOURCE@, @COMPILE@. Always use `-o $@'. (@LTOBJ@): Likewise. * automake.in (handle_single_transform_list): Don't print rule if doing dependency tracking and the file's language supports it. (initialize_per_input): Initialize lang_specific_files. (add_depend2): New function. (handle_dependencies): Use it. * automake.in (lang_ppf77_finish): Use lang_f77_finish. ratfor compiler name is `RCOMPILE'. ppf77 compiler name changed to `PPF77COMPILE' to allow use of f77 and ppf77 in the same directory. (lang_ratfor_finish): Use lang_f77_finish. * compile.am (NOTDEPEND.c.o): Removed. (OBJEXT.c.obj): Likewise. * automake.in: Added `flags' attribute to all relevant languages. (handle_single_transform_list): Handle per-derived-object flags. Changed interface and all callers. (handle_built_sources): Don't call handle_single_transform_list. Added `compile' and `compiler-name' attribute to all relevant languages. (finish_languages): Define compiler variables here. (lang_cxx_finish): Don't call define_compiler_variable. Don't define flag variable or .o rules. Don't add to @suffixes. (lang_f77_finish): Likewise. (lang_ppf77_finish): Likewise. (lang_objc_finish): Likewise. (lang_java_finish): Likewise. (finish_languages): Define flag variable here. Added `output-arg' attribute to all relevant languages. (finish_languages): Define `.o' rules here. (finish_languages): Put extension on @suffixes. (get_object_extension): Don't transform NOTDEPEND or MINUSO.

## There are various ways to get dependency output from gcc.  Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
##   up in a subdir.  Having to rename by hand is ugly.
##   (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
##   -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse
##   than renaming).
	@COMPILE@ -Wp,-MD,.deps/$(*D)/$(*F).pp -c -o $@ $<
## This next piece of magic avoids the `deleted header file' problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header).  We avoid this by adding
## dummy dependencies for each header file.  Too bad gcc doesn't do
## this for us directly.
	@-cp .deps/$(*D)/$(*F).pp .deps/$(*D)/$(*F).P; \
	tr ' ' '\012' < .deps/$(*D)/$(*F).pp \
## Some versions of gcc put a space before the `:'.  On the theory
## that the space means something, we add a space to the output as
## well.
