There's more than those two and they're from makefiles, not automake specifically.

See Makefile variable assignment

    Note that if you use a `:=` assignment with `-Wall` passed to `AM_INIT_AUTOMAKE`, you get the following error: `Makefile.am:12: \`:='-style assignments are not portable` – Jack Kelly Nov 06 '10 at 10:37
