d9291d09b8 Use strtol() instead of atoi()
strtol() is part of C89 and a fallback is provided by gnulib.

* src/function.c (func_word, func_wordlist): Change atoi to strtol.
* test/scripts/functions/word: Add out-of-range verification testing.

f8f9d371ff [SV 61042] Enhance logging of implicit rule search
Logging of implicit rule search gives limited information as to why a
given implicit rule was rejected, and if no implicit rule is found we
get the confusing "No rule to make target" result when the real issue
is that some prerequisite of some implicit rule could not be built.

Enhance logging around implicit rule search as follows:
1. The messages which refer to a rule print a description (the targets
   and prerequisites) of the rule.
2. A new message tells when a rule is rejected, along with the reason.
3. The 'Looking for an implicit rule...' message is printed for every
   prerequisite, not just the top-level target.
4. "Trying harder" message is printed, when intermediate prerequisites
   are going to be searched.
5. The 'No rule found...' and 'Found implicit rule...' messages are
   printed for every prerequisite, not just the top-level target.
6. "Ought to exist...", "Found..." or "Not found..." message is
   printed for each prerequisite.

* src/rule.h (struct rule): Remember the definition of the rule.
* src/rule.c (get_rule_defn): Compute the definition of a rule.
(install_pattern_rule): Initialize the definition to empty.
(create_pattern_rule): Ditto.
(freerule): Free the definition.
(print_rule): Use the definition when printing rules.
* src/remake.c (update_file_1): Push debug output down into
try_implicit_rule().
* src/implicit.c (try_implicit_rule): Add debugging
(pattern_search): Show the rule definition in various debug output.
Add new debug messages for implicit rule search.

Additional changes by Paul Smith <psmith@gnu.org>:

Since we usually don't need the rule definition, defer computing it
until we do.

* bootstrap.conf: Include the mempcpy Gnulib module.
* src/makeint.h (mempcpy): Declare mempcpy if not available.
* src/misc.c (mempcpy): Define mempcpy if not available.
* src/config.h-vms.template: Don't set HAVE_MEMPCPY.
* src/config.h.W32.template: Ditto.
* src/rule.h (get_rule_defn): Return the definition of a rule.
* src/rule.c (get_rule_defn): If we don't have a definition compute
it; either way return it.
* src/implicit.c (pattern_search): Rework the handling of explicit
prerequisites to pattern rules to be more clear.  There is no change
in behavior.

60905a8afb [SV 56834] Support local PATH search with posix_spawnp
When using exec we install the child's environment before invoking
execlp(), so commands are found on the child's PATH.  posix_spawnp
searches on the parent's PATH, which we don't want.

Import gnulib's findprog-in module and use it to search the child's
PATH, then use posix_spawn() to run it.

Also, posix_spawn() does not fall back to trying sh on ENOEXEC, as
execlp() does, so implement that as well.

* bootstrap.conf: Add the findprog-in gnulib module
* src/job.c: Include findprog.h if we're using posix_spawn.
(start_job_command): Remove the handling of child->cmd_name,
(child_execute_job): and add it here.  Look up the command to be
run in the child's path and invoke it if found.  If it fails with
ENOEXEC then retry it as an argument to the default shell.
* tests/scripts/misc/general4: Test makefile PATH assignments.
* tests/scripts/features/targetvars: Ditto, for target variables.

63b42fa235 Convert GNU make to use the gnulib portability library
Move content from glob/* and config/* into standard GNU directory
locations lib/* and m4/*.

Install the gnulib bootstrap script and its configuration file, and
create a bootstrap.bat file for Windows.  Update the README.git file
with new requirements and instructions for building from Git.

At this point we only install the alloca, getloadavg, and FDL modules
from gnulib.  We keep our old glob/fnmatch implementation since the
gnulib versions require significant amounts of infrastructure which
doesn't exist on Windows yet.  Further work is required here.

Due to a problem with gnulib's version of getloadavg, we need to bump
the minimum required version of automake to 1.16.1 unfortunately.

* README.git: Update instructions
* NEWS: Move developer news to a separate section
* configure.ac: Update for use with gnulib modules

* bootstrap: Bootstrap from Git workspace (import from gnulib)
* bootstrap.conf: Bootstrap configuration for GNU make
* bootstrap.bat: Bootstrap from Git workspace for Windows
* gl/modules/make-glob: Support our local fnmatch/glob implementation

* config/acinclude.m4: Move to m4/
* config/dospaths.m4: Move to m4/
* glob/fnmatch.c: Move to lib/
* glob/fnmatch.h.in: Move to lib/
* glob/glob.c: Move to lib/
* glob/glob.h.in: Move to lib/

* Makefile.am: Update for new directories
* build.template: Update for new directories

* po/LINGUAS: One language per line (needed by gnulib)

* INSTALL: Remove (obtained from gnulib)
* src/alloca.c: Remove (obtained from gnulib)
* src/getloadavg.c: Remove (obtained from gnulib)
* po/Makevars: Remove (created by bootstrap)
* config/*: Remove leftover files
