If you have to support non-GNU make programs, you can't achieve this
with one literal line.  Some non-GNU makes may need '.include' instead
of 'include', and some need quotes.  Exploiting an undocumented Automake
feature (please don't complain if upgrading breaks it), you can use
  @am__include@ @address@hidden@am__quote@

(these substitutions will be generated if you use automatic dependency
tracking; otherwise, you may need to call the undocument AM_MAKE_INCLUDE
macro yourself).

Cheers,
Ralf
