* libltdl/m4/ltdl.m4 (LT_WITH_LTDL, LTDL_CONVENIENCE)

Browse Source 
(LTDL_INSTALLABLE): Use less quoting for expanded LIBLTDL,
LTDLINCL.  Use m4_default instead of m4_if, to work
around AU_ALIAS bug with empty macro arguments.
(LTDL_INIT): Likewise.
* libltdl/m4/ltoptions.m4 (_LT_WITH_PIC): Likewise.
* TODO, HACKING: Updated.
