Some fixes for KNR compilers:

        * gencheck.c: Remove redundant stdio.h include.  Add a definition
        of xmalloc for when we are forced to link with alloca.o.
        * reload1.c (reload_reg_free_for_value_p): Use `(unsigned)1'
        instead of `1U'.
        * fold-const.c (constant_boolean_node): Make definition static to
        match the prototype.
