powerpc-linux-gcc compiler error: undefine reference to "__va_arg_type_violation"

[dony]

Hi,
    When I compile my kernel , it reports in vsprintf:
    Undefined reference to "__va_arg_type_violation".

My cross environment is:
 gcc-2.95.2
 glibc-2.1.2
 binutils-2.9.5.0.22
 gcc-core-2.95.2

But when I use the following environment , It can build my kernel sucessfully:

binutils-2.9.1.0.19a
egcs-core-1.1.2.tar.gz
glibc-2.1.tar.gz

Does anybody know why?

TIA
dony
