Subject: bootstrap: accept --gnulib-srcdir=/path/to/gnulib again.
X-Git-Tag: v2.4.2.418~270
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7285b13522e6ceae95b571e5fed8c900dc9a6ead;p=thirdparty%2Flibtool.git

bootstrap: accept --gnulib-srcdir=/path/to/gnulib again.

During the split of bootstrap into options-parser and
extract-trace, the generic long-option splitting code got lost.
* libltdl/config/options-parser (func_parse_options): Add the
code to split any long option separated by an equals from its
optarg back in.
Reported by Roumen Petrov.
