Subject: Libtoolize now advises AC_CONFIG_MACRO_DIR use where appropriate.
X-Git-Tag: v2.2.4~14
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=4d777f8223aabcd4ff95aefe8fd3fb86f5e6d7ae;p=thirdparty%2Flibtool.git

Libtoolize now advises AC_CONFIG_MACRO_DIR use where appropriate.

* libtoolize.at (func_check_macros): Always advise use of
AC_CONFIG_MACRO_DIR when not able to copy libtool macros into
the project tree.
* tests/libtoolize.at: New test for correct diagnosis of mismatch
between AC_CONFIG_MACRO_DIR and ACLOCAL_AMFLAGS.
Update expected output of other tests.
* NEWS: Updated.

     diagnoses only the macro files that are missing or not up-to-date.
