build fix glibc-2.3.2/ gcc 3.3.2

[Rainer Weikusat]

gcc 3.3.2 refuses to compile glibc-2.3.2 because
sscanf (from stdio-common) is a K&R-style function
declared w/o ... and the compiler complains about
'va_list used in non-variadic function' (this is not
the exact text of the message). The follwing patch
corrects this:
