POSIX says that suffix rules cannot have prerequisites, but after making this change we observed a number of makefiles "in the wild" that were relying on this behavior and failed. For .POSIX: makefiles, obey POSIX. Otherwise preserve the old behavior. However, generate a warning so users know this is a problem. In a future version we will change all behavior to be POSIX-conforming. * NEWS: describe the change * src/rule.c (convert_to_pattern): If posix_pedantic don't make a pattern rule if prereqs exist. Otherwise show a warning. * tests/scripts/features/suffixrules: Add tests for the new behavior including .POSIX vs. non-.POSIX.
