Well, suffixes containing slashes or periods (other than the
leading one) are not covered by POSIX make; I don't know which
make implementations need this restriction though.

You can try playing with VPATH.  But note that Automake uses VPATH for
$(srcdir) so you may find it less error-prone to just put the %.lang
files in $(srcdir).

Hope that helps.
