* configure.in (host_xm_file, build_xm_file): Include hwint.h.
Use case statements instead of "if test -a ... -a ... -a ..."
* machmode.h: Don't define HOST_WIDE_INT, etc. Wrap use of
HOST_WIDE_INT in #ifdef.

HOST_WIDE_INT, etc. Wrap uses of HOST_WIDE_INT in #ifdef.

Redesign GCC_FUNC_PRINTF_PTR so that it doesn't define HOST_PTR_PRINTF
directly. Instead, autoconf will only determine whether "%p" works and
its up to machmode.h to base its definition of HOST_PTR_PRINTF on that.
This ensures that machmode.h is always included to get the definition of
HOST_PTR_PRINTF for lossy hosts or cross compiles where "%p" is not
found.
* aclocal.m4 (GCC_FUNC_PRINTF_PTR): Don't define HOST_PTR_PRINTF.
Instead, define a new macro HAVE_PRINTF_PTR which only signifies
whether we have the %p format specifier or not.
* acconfig.h: Delete stub for HOST_PTR_PRINTF, add HAVE_PRINTF_PTR.
* machmode.h (HOST_PTR_PRINTF): When determining the definition,
check HAVE_PRINTF_PTR to see whether "%p" is okay.
* mips-tfile.c: Include machmode.h to get HOST_PTR_PRINTF.
* Makefile.in (mips-tfile.o): Depend on machmode.h.
