OK, I must admit to be stuck here.  How can I know what objects files 
are expected to be compiled from, say, a bar.c file, in turn generated
from a bar.l file?

Or (e.g.) how can I distinguish the following situation:

  foo_SOURCES = bar.l

(where bar.c is generated from bar.l, bar.o is generated from bar.c,
and no explicit dependency rule is generated), from the following
situation:

  foo_SOURCES = bar.l
  foo_CFLAGS =  $(AM_CFLAGS)

(where bar.c is generated from bar.l, and foo-bar.o is generated from 
bar.c, with an explicit dependency rule of foo-bar.o from bar.c)?

Thanks,
