Are you looking for something like this?

check-srcdir-files-not-in-dist: distdir
        diff -rq $(srcdir) $(distdir)

(the -q is GNU-specific)

It is bound to have false positives (backup files, version control meta
files and other files you don't want distributed (yet)), as well as
false negatives (in case your build tree is equal to, or below, your
source tree; in case you distribute files from the build tree).  Other
than that, I wouldn't know how Automake should be able to know which
files you want distributed and which errors result from missing files.

Generally it's a good idea to list sources (including headers) in
*_SOURCES variables; that way, they are automatically distributed,
and you only need to list them once (not sure if that applies here).

Cheers,
Ralf
