commit a5ef08182ce0fb80b8adcff5872f190afd915908

Date:   Wed Nov 16 12:13:55 2011 +0700

    bootstrap: display accurate usage message.
    
    After splitting bootstrap up, we also lost bootstraps usage
    message, and were incorrectly displaying a partial extract-trace
    message.
    * bootstrap (usage): Set appropriately.

commit 7285b13522e6ceae95b571e5fed8c900dc9a6ead

    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.
