From: Stefano Lattarini Date: Thu, 26 Jan 2012 18:00:40 +0100 Subject: [PATCH] warnings: more precise category and message for one warning If automake detected an usage like "AC_CONFIG_FILES([./Makefile])" in configure.ac, it warned that such an usage was unportable to non-GNU make implementations. But the truth is actually worse: that is actually *unportable to GNU make* itself, since it breaks the automatic remake rules in subtle ways. So we now reveal this breakage in a new test case, and enhance the warning by giving it a more precise and correct wording, and by moving it from the category 'portability' to the category 'unsupported'. * automake.in (scan_autoconf_config_files): Improve the warning. * tests/conffile-leading-dot.test: New test. * tests/list-of-tests.mk: Add it. --- automake.in | 9 +++-- tests/conffile-leading-dot.test | 62 +++++++++++++++++++++++++++++++++++++++ tests/list-of-tests.mk | 1 + 3 files changed, 68 insertions(+), 4 deletions(-) create mode 100755 tests/conffile-leading-dot.test diff --git a/automake.in b/automake.in index abca23d..cdbb820 100644 --- a/automake.in +++ b/automake.in @@ -5253,10 +5253,11 @@ sub scan_autoconf_config_files ($$) # Handle $local:$input syntax. my ($local, @rest) = split (/:/); @rest = ("$local.in",) unless @rest; - msg ('portability', $where, - "Omit leading `./' from config file names such as `$local'," - .
