Suffix rules with dependencies

[Eli Zaretskii]

In this thread:

   http://lists.gnutls.org/pipermail/gnutls-devel/2013-September/006453.html

and specifically in this message and its followups:

  http://lists.gnutls.org/pipermail/gnutls-devel/2013-September/006460.html

there's evidence that GNU Make no longer treats suffix rules with
prerequisites "as normal files with funny names", as described in the
manual.

Did the behavior indeed change, and if so, in what version of Make?  I
couldn't find anything in NEWS, FWIW.

TIA
