v1.13.1-109-g030ecb4 of 2013-01-16, "compat: restore
AM_PROG_MKDIR, again", for the rationale.
Signed-off-by: Stefano Lattarini <stefano.lattarini@gmail.com>
* Obsolete features removed:
- - The long-obsolete (since automake 1.10) AM_PROG_MKDIR m4 macro has
- been removed. The $(mkdir_p) make variable and the @mkdir_p@
- substitutionl still remains available for the moment, as aliases
- of $(MKDIR_P), for better backward compatibility; but you are
- advised to stop using ASAP, as they might be removed in future
- Automake versions.
-
- Support for the long-deprecated name 'configure.in' for the Autoconf
input file has been removed altogether. Just use the modern name
'configure.ac' instead.
