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.
