rathann e7db4ccf1a Patch by Stefan Huehner / stefan % huehner ! org \ 
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

* Motion Compensation frequently needs to average values using the
* formula (x+y+1)>>1. Both MMXEXT and 3Dnow include one instruction
* to compute this, but it's been left out of classic MMX.
*
* We need to be careful of overflows when doing this computation.
* Rather than unpacking data to 16-bits, which reduces parallelism,
* we use the following formulas:
*
* (x+y)>>1 == (x&y)+((x^y)>>1)
* (x+y+1)>>1 == (x|y)-((x^y)>>1)
