Joseph Myers 41075ae3e7 Convert 29 more function definitions to prototype style (multiple parameters in one K&R parameter declaration).
This automatically-generated patch converts 29 function definitions in
glibc (including one in an example in the manual) from old-style K&R
to prototype-style.  Following my other recent such patches, this one
deals with the case of function definitions where one K&R parameter
declaration declares multiple parameters, as in:

void
foo (a, b)
     int a, *b;
{
}

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

	definition.
