Subject: * libtoolize.m4sh: Use serial tags to locate the correct serial
X-Git-Tag: release-2-1b~438
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c215fede13e2eda941a3607424e4f3cb34012064;p=thirdparty%2Flibtool.git

* libtoolize.m4sh: Use serial tags to locate the correct serial
numbers when deciding whether to update.
(func_serial): Allow for macro_regex argument to be originating
file name.
(func_serial_update): Use NL2SP to flatten list of extracted
m4_include files.
* tests/libtoolize.at: More tests for old-style verbatim copying
of macros into aclocal.m4.
