    * doc/make.text: [SV 54360] Weaken "obsolete" language in the manual.
    
    There's no need to frighten users away from capabilities which are
    perfectly reasonable and definitely not going away, by calling them
    obsolete or discouraged in the manual.

    [SV 40657] Don't create pattern rules for suffix rules with deps.
    
    * NEWS: Update with a backward-compatibility warning.
    * src/rule.c (convert_to_pattern): If a suffix rule has dependencies,
    do not create a pattern rule for it.  According to the manual suffix
    rules with prerequisites are treated as normal targets.
    * tests/scrips/features/suffixrules: Create some regression tests for
    .SUFFIXES and suffix rules.
