This partially reverts my 2016-05-30 patch. Apparently MinGW64
still requires pacifications that GCC 7.1.1 x86-64 (Fedora 26)
does not. Also, pacify tparam.c, which isn’t used on Fedora.
* lib-src/etags.c (process_file_name, TeX_commands):
* src/buffer.c (fix_overlays_before):
* src/data.c (Fmake_variable_buffer_local, cons_to_unsigned)
(cons_to_signed):
* src/editfns.c (Ftranslate_region_internal):
Prefer UNINIT to some stray value, as this simplifies
code-reading later.
* src/eval.c (CACHEABLE): New macro.
(internal_lisp_condition_case): Use it.
* src/tparam.c (tparam1): Use FALLTHROUGH to pacify GCC.

* src/data.c (Ftype_of): Do not worry about Lisp_Misc_Float.
* src/lisp.h (Lisp_Misc_Float): Remove. This placeholder has been
unused for two decades; if we ever want to change floats to be a
misc type we can bring it back then.

Instead of a lambda, create a new type containing all data required to
call the function, and support it in the evaluator. Because this type
now also needs to store the function documentation, it is too big for
Lisp_Misc; use a pseudovector instead. That also has the nice benefit
that we don't have to add special support to the garbage collector.
Since the new type is user-visible, give it a predicate.
Now we can easily support 'help-function-args' and 'func-arity'; add
unit tests for these.
* src/lisp.h (allocate_module_function, MODULE_FUNCTIONP)
(XMODULE_FUNCTION): New pseudovector type 'module function'.
* src/eval.c (FUNCTIONP): Also treat module functions as functions.
(funcall_lambda, Ffuncall, eval_sub): Add support for calling module
functions.
(Ffunc_arity): Add support for detecting the arity of module
functions.
* src/emacs-module.c (module_make_function): Adapt to new structure.
Return module function object directly instead of wrapping it in a
lambda; remove FIXME.
(funcall_module): New function to call module functions. Replaces
`internal--module-call' and is called directly from eval.c.
(syms_of_module): Remove internal helper function, which is no longer
needed.
(module_function_arity): New helper function.
* src/data.c (Ftype_of): Adapt to new implementation.
(Fmodule_function_p, syms_of_data): New user-visible function. Now
that module functions are first-class objects, they deserve a
predicate. Define it even if not compiled with --enable-modules so
that Lisp code doesn't have to check for the function's existence.
* src/doc.c (Fdocumentation): Support module functions.
* src/print.c (print_object): Adapt to new implementation.
* src/alloc.c (mark_object): Specialized garbage collector support is
no longer needed.
* lisp/help.el (help-function-arglist): Support module functions.
While there, simplify the arity calculation by using `func-arity',
which does the right thing for all kinds of functions.
* test/data/emacs-module/mod-test.c: Amend docstring so we can test
the argument list.
* test/src/emacs-module-tests.el (mod-test-sum-docstring): Adapt to
new docstring.
(mod-test-non-local-exit-signal-test): Because `internal--module-call'
is gone, the backtrace has changed and no longer leaks the
implementation.
(module--func-arity): New test for `func-arity'.
(module--help-function-arglist): New test for `help-function-arglist'.

* src/data.c (ash_lsh_impl): Verify that signed right shift is
arithmetic; if we run across a compiler that uses a logical shift
we’ll need to complicate the code before removing this
compile-time check. Help the compiler do common subexpression
elimination better.

This incorporates:
2017-05-16 manywarnings: update for GCC 7
2017-05-15 sys_select: Avoid "was expanded before it was required"
* configure.ac (nw): Suppress GCC 7’s new -Wduplicated-branches and
-Wformat-overflow=2 options, due to too many false alarms.

* src/gtkutil.c (xg_check_special_colors):
When using sprintf, don’t trust Gtk to output colors in [0, 1] range.
(xg_update_scrollbar_pos): Avoid use of possibly-uninitialized bool;
this bug was actually caught by Clang.
* src/search.c (boyer_moore):
Tell GCC that CHAR_BASE, if nonzero, must be a non-ASCII character.
* src/xterm.c (x_draw_glyphless_glyph_string_foreground):
Tell GCC that glyph->u.glyphless.ch must be a character.

This puts basic functions for types to be after the corresponding
type definitions. This is a more-common programming style in C,
and will make it easier to port Emacs to gcc
-fcheck-pointer-bounds, since the functions now have access to the
corresponding types' sizes. This patch does not change the code;
it just moves declarations and definitions and removes
no-longer-needed forward declarations (Bug#25128).
* src/buffer.c, src/data.c, src/image.c:
Include process.h, for PROCESSP.
* src/buffer.h (BUFFERP, CHECK_BUFFER, XBUFFER):
* src/process.h (PROCESSP, CHECK_PROCESS, XPROCESS):
* src/termhooks.h (TERMINALP, XTERMINAL):
* src/window.h (WINDOWP, CHECK_WINDOW, XWINDOW):
* src/thread.h (THREADP, CHECK_THREAD, XTHREAD, MUTEXP, CHECK_MUTEX)
(XMUTEX, CONDVARP, CHECK_CONDVAR, XCONDVAR):
Move here from lisp.h.
* src/intervals.h: Include buffer.h, for BUFFERP.
Include lisp.h, for Lisp_Object.
* src/lisp.h: Reorder declarations and definitions as described
above. Move thread includes to be later, so that they can use the
reordered definitions. Move some symbols to other headers (noted
elsewhere). Remove forward decls that are no longer needed.
* src/thread.h: Include systhread.h here, not in lisp.h,
since lisp.h itself does not need systhread.h.
