+ gitlog-to-changelog: new auxiliary script, synced from gnulib
+
+ We have plans to stop maintaining a version-controlled ChangeLog

+ the `gitlog-to-changelog' script from gnulib.

+ docs: "aclocal --install -I /abs/dir" actually copies files
+
+ This change is for automake bug#8407.
+
+ In the past, there had been some debate and confusion about
+ whether "aclocal --install" should copy third-party .m4 files
+ in the first directory passed to the `-I' option even when
+ such directory was given as an absolute path, or whether it
+ was better to do so only for directories specified with a
+ relative path.
+
+ The rationale for this latter behaviour was that, before the
+ existence of the `ACLOCAL_PATH' variable, the only way (a poor
+ way, I might add) for a common user to extend the search path
+ of a system-wide installation of aclocal was to export something
+ like ACLOCAL="aclocal -I /my/extra/macros" in the environment.
+ Today, the correct way to proceed is undoubtedly through the
+ use of ACLOCAL_PATH, so we can settle the question once and for
+ all, and start verifying the correct behaviour of `-I' with a
+ new test.
+
+ * tests/aclocal-install-absdir.test: New test.
+ * tests/Makefile.am (TESTS): Add it.
+ * doc/automake.texi (aclocal Options): Be more explicit about
+ this part of `--install' semantics.

+
+ docs: fix node names for automake and aclocal invocations
+
+ With the older node names, an "info automake" command issued
+ from the command line would have opened the node about the
+ invocation of the automake program, rather than the Top node
+ of the automake documentation. To invoke the Top node, one
+ had to issue the command "info Automake" instead (note the
+ different capitalization). This was suboptimal, and certainly
+ confusing.
+
+ With this change, "info automake" will open the Top node of the
+ automake documentation; to access the nodes about the invocation
+ of the automake and aclocal program, one has now to issue "info
+ automake-invocation" and "info aclocal-invocation" respectively.
+
+ This change fixes automake bug#8071.
+
+ See also commits `v2.61a-22-ge9215d1' and `v2.61a-72-g8c07b48' in
+ the autoconf git repository, which tackled a similar issue.
+
+ * doc/automake.texi (@direntry): Rename nodes `aclocal' and
+ `automake' to `aclocal-invocation' and `automake-invocation'
+ respectively.
+ * NEWS: Update.

+ tests: tweak tests on silent-rules for makes without nested vars
+ * tests/silent-nested-vars.test: Define $MAKE to `./mymake' in
+ the environment, so that it will be automatically picked up by
+ configure. Related tweaks and simplifications.
+ Remove the checks verifying that silent rules are respected also
+ when the 'subdir-objects' option is set, the checks testing the
+ old syntax for user-defined silent rules, and the tests using
+ the default $MAKE programs: they are redundant w.r.t. other test
+ cases. Related simplifications.
+ Remove the temporary files used in a sanity check as soon as they
+ are not needed anymore.
+ Do not capture also the standard error of configure: we only want
+ to grep its standard output.
+ Consistently use `stdout' for the name of files where to save the
+ standard output captured from make and configure, for consistency
+ with other tests.
+ Make grepping of configure output and of the generated Makefile
+ stricter.
+ Improve and tweak the `mymake' script a little.
+ * tests/silent6.test: Make grepping of make stdout slightly
+ stricter. After having configured with silent rules disabled,
+ try to force the use silent rules with `make V=1'.

+ silent-rules: fallback for makes without nested vars
+
+ This fixes two problems reported for Automake (Bug#9928, Bug#10237)
+ and is in response to a bug report for building coreutils on HP
+ NonStop OS (Bug#10234). The problem is that HP NonStop 'make'
+ treats a line like "AM_V_CC = $(am__v_CC_$(V))" as one that
+ expands a macro with the funny name am__v_CC_$(V instead of the
+ desired name am__v_CC_1 or am__v_CC_0, and since the funny macro
+ is not defined the line is equivalent to "AM_V_CC = )"; this
+ inserts a stray ")" when $(AM_V_CC) is used, which eventually
+ causes 'make' to fail.
+
+ The basic idea is that instead of generating Makefile.in lines like
+ "AM_V_CC = $(am__v_CC_$(V))", we generate
+ "AM_V_CC = $(am__v_CC_@AM_V@)". We then AC_SUBST $(V) for @AM_V@
+ in the usual case where `make' supports nested variables,
+ and substitute 1 (or 0) otherwise. Similarly for usages like
+ $(am__v_CC_$(AM_DEFAULT_VERBOSITY)).
+
+ With this change, make implementations that doesn't grasp nested
+ variable expansions will still be able to run Makefiles generated
+ using the silent-rules option. They won't allow the user to
+ override the make verbosity at runtime through redefinition of
+ $(V) (as in "make V=0"); but this is still an improvement over not
+ being able to work at all.
+
+ * NEWS: Document this.
+ * automake.in (define_verbose_var): When defining the variables,
+ use @AM_V@ rather than $(V), and use @AM_DEFAULT_V@ rather than
+ $(AM_DEFAULT_VERBOSITY).
+ * doc/automake.texi (Automake silent-rules Option): Explain new system.
+ * m4/silent.m4 (AM_SILENT_RULES): Check whether `make' supports
+ nested variables, and substitute AM_V and AM_DEFAULT_V accordingly.
+ * tests/silent-nested-vars.test: New test.
+ * tests/Makefile.am (TESTS): Add it.
