- version bump
- Dependency tracking using mode "dashmstdout" or "dashXmstdout" did not
work for libtool objects compiled with --tag (i.e., compiled with
Libtool 1.5 or later). The compilation would succeed, but `depcomp'
would emit a warning and not output any dependency information.
- Ignore comments from augmented variables ...
- `install-sh -d a/b/' failed to create `a/b/' because of the trailing `/'.
- _PROGRAMS now always create programs. Before 1.9 it would mistakenly
create a libtool library if the name of the program ended in `.la'.
- `compile' now handles `*.obj' objects.
- `aclocal' recognizes AC_DEFUN_ONCE.
