since this is new code, can you avoid recurisve makes ?  rename the subdir
Makefile.am to local.mk and include them in this Makefile.am instead.

you don't actually use this anywhere

you called AC_USE_SYSTEM_EXTENSIONS, so why do you need to use -D_GNU_SOURCE ?

most other projects have already moved to C11.  why do you have to use such
an ancient version ?

you should be using $(AM_CPPFLAGS) instead of manually duplicating the value

you're setting ACLOCAL_AMFLAGS already.  pretty sure you don't need these.

why do you need this logic ?  isn't this covered by AM_MAINTAINER_MODE ?

use `dnl` for comments, not `#`

this project is new.  why aren't the warnings fixed to begin with ?

you already probed -Wall above.  do you really need to do it again ?

you aren't using most of this.  are you just copying & pasting from another
tree ?

do you actually need this ?

this style complicates things.  use:

check_PROGRAMS =
if HAVE_COMPAT_DEJAGNU
check_PROGRAMS += ...
endif
