+ * libltdl/m4/libtool.m4 (_LT_COMPILER_BOILERPLATE)
+ (_LT_LINKER_BOILERPLATE, _LT_COMPILER_OPTION, _LT_LINKER_OPTION)
+ (_LT_COMPILER_C_O): When comparing expected and actual compiler/
+ linker output for warnings, weed out both empty lines as well as
+ lines starting with possibly indented `+', to allow for shell
+ debugging with `set -x'.
+ Check the weeded instead of unweeded contents for emptiness.
+
* libltdl/config/ltmain.m4sh (func_mode_link): Actually provide
a useful error message. Fixes long-standing shameful user
neglection.
