patch replaces '()' for the correct '(void)' in function declarations/prototypes which have no parameters. The '()' syntax tell thats there is a variable list of arguments, so that the compiler cannot check this. The extra CFLAG '-Wstrict-declarations' shows those cases. Comments about a similar patch applied to ffmpeg: That in C++ these mean the same, but in ANSI C the semantics are different; function() is an (obsolete) K&R C style forward declaration, it basically means that the function can have any number and any types of parameters, effectively completely preventing the compiler from doing any sort of type checking. -- Erik Slagter Defining functions with unspecified arguments is allowed but bad. With arguments unspecified the compiler can't report an error/warning if the function is called with incorrect arguments. -- Måns Rullgård git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@17567 b3059339-0415-0410-9bf9-f77b7e298cf2
