 @code{sniff-glue}, the derived variable name would be
 @code{sniff_glue_SOURCES}, not @code{sniff-glue_SOURCES}.
 
+Additionally, because some versions of make require macro names to start
+with a @emph{letter}, when a name that starts with a non-letter
+character is canonicalized, the characters @code{AM} are prepended to
+it.  Therefore, if a program is named @code{123test} or @code{_foo}, the
+derived variable names would be @code{AM123test_SOURCES} or
+@code{AM_foo_SOURCES}.  Note that, even if such a program name would not
+appear in the beginning of the name of the macro, @code{AM} is still
+inserted, i.e., use @code{EXTRA_AM123test_SOURCES}, not
+@code{EXTRA_123test_SOURCES}.
