DEP_FILES not being set if *_SOURCES has more than one *.h file

[Raja R Harinath]

Hi,

After a recent change to automake.in, automake stops tracking
dependencies if there is more than one header file listed in a
*_SOURCES primary.

I've attached a testcase and a suggested fix.

        * automake.in (saw_sources_p): Work even if there are more
        than one header files, and more than of one type of header.

Description: Fix for saw_sources_p
