Subject: * libltdl/m4/libtool.m4 (_LT_COMPILER_BOILERPLATE)
X-Git-Tag: release-2-1b~522
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ba0a5124be425210cdef584acab8113cdd402327;p=thirdparty%2Flibtool.git

* 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.

 	a useful error message.  Fixes long-standing shameful user
 	neglection.
