Naah.  For things that you only ever specify as prerequisites, never as
targets, don't spell out the `$(srcdir)/', but let VPATH do its work.

Whenever you specify a file anywhere with `$(srcdir)/' as target or
prerequisite (and many of Automake's special variables end up being
prerequisites to some target), then do it consistently everywhere.

HTH.

Cheers,
Ralf
