It was this bit in Makefile.am that seems odd to me:

# note that we cannot just use AC_OUTPUT to do this for us, since it
will do things like this:
# LD_LIBRARY_PATH = ${prefix}/lib/fedora-ds
# i.e. it literally copies in '${prefix}' rather than expanding it out -
we want this instead:
# LD_LIBRARY_PATH = /usr/lib/fedora-ds
if BUNDLE
fixupcmd = sed \
        -e 's,@bindir\@,$(bindir),g' \
        -e 's,@sbindir\@,$(sbindir),g' \

It seems odd because it is odd - but there is no other way to replace things like @localstatedir@, @sysconfdir@, @sbindir@, etc. in .in files that we use during the build. I don't know how other projects do this - perhaps they ignore the "mandated GNU coding standards" and just have ${prefix} and ${exec_prefix} expanded during configure, and just let AC_CONFIG_FILES and AC_OUTPUT create all of the real files from their corresponding .in file.

I think so.  The coding standard seems to imply that you must be able to
change the $prefix and $exec_prefix in the install, but that all
internal references must be as if they had *not* been changed.
So, let me see if I understand what you're saying. Let's say I have some .in files which have references to @prefix@ and @bindir@ (which is ${prefix}/bin). I run configure which creates realfile from realfile.in - I don't pass in --prefix to configure, which means @prefix@ will expand to "/usr" and @bindir@ to "/usr/bin" in realfile. Next, I run make prefix=/myprefix install. realfile will still refer to "/usr" even though I've told make to use "/myprefix" instead.

Where does it say or imply that? Isn't that what "make DESTDIR=/path install" for?
Perhaps
that's the clue?
