configure.in: Move check for unsigned enumerated bitfields to macro in aclocal.m4.
* configure.in: Move check for unsigned enumerated bitfields
to macro in aclocal.m4. Disable it for now.
* configure, config.in: Regenerate.
* system.h: Don't do anything with ONLY_INT_FIELDS. Use the
unsigned-int form of ENUM_BITFIELD() unless being compiled by GCC.
* varasm.c (struct rtx_const): Use ENUM_BITFIELD(). Move enum
kind above its first use.
* config/xm-interix.h, config/alpha/xm-alpha.h,
config/i370/xm-linux.h, config/i386/xm-beos.h,
config/i386/xm-mingw32.h, config/mips/xm-mips.h,
config/pa/xm-pa.h, config/pa/xm-pa64hpux.h,
config/rs6000/xm-beos.h, config/rs6000/xm-sysv4.h,
Don't define ONLY_INT_FIELDS under any circumstances.
* config/pa/xm-pa.h: Don't define __BSD_NET2__.
* config/pa/xm-pahpux.h, config/pa/xm-papro.h,
config/sparc/xm-sysv4.h: Delete - now identical with some
other xm header.
* config.gcc (hppa targets): Replace xm-pahpux.h and
xm-papro.h with implicit xm-pa.h.
(sparc targets): Replace xm-sysv4.h with implicit or explicit
xm-sparc.h.
