ACPICA commit be836c36454a624a4fb1d17234080ef8c07993fc There is a GCC false-warning issue on specific GCC versions that "strchr" will be preprocessed and extracted to contain !__buildin_constant_p() checker and it surely is a constant logical value "1" for strchr() arguments. Then -Wlogical-op errorneously reports a warning. The regression is triggered after the standard headers are re-ordered in the EFI porting task. This patch fixes this regression by moving the workaround to a new position after including all other standard headers.
