automake warning

[Robert Vollmert]

When I run `make` in the guix repository, I always get the following
block of warnings at the start:

configure.ac:23: warning: The 'AM_PROG_MKDIR_P' macro is deprecated, and its 
use is discouraged.
configure.ac:23: You should use the Autoconf-provided 'AC_PROG_MKDIR_P' macro 
instead,
configure.ac:23: and use '$(MKDIR_P)' instead of '$(mkdir_p)'in your 
Makefile.am files.
Makefile.am:613: warning: AM_GNU_GETTEXT used but 'po' not in SUBDIRS

I tried figuring out what’s wrong, but am a bit at a loss. Web search indicates 
this might
have to do with an old gettext version, but that info is from several years, 
and should have
been fixed for a while. Any ideas?
