    The changes to the tm.h files are trivial, so I don't think this
    really needs approval from the various platform maintainers.

	    Bring IEEE_FLOAT under gdbarch's control.
	    * gdbarch.sh (IEEE_FLOAT): New entry.
	    * gdbarch.c, gdbarch.h: Regenerated.

	    * valprint.c (IEEE_FLOAT): Provide a default #definition for this.
	    (print_floating): Use IEEE_FLOAT as if it were an expression; use
	    the code specific to IEEE-format numbers whenever the value of
	    IEEE_FLOAT is non-zero.

The valprint.c part is approved.

	    * config/a29k/tm-a29k.h, config/alpha/tm-alpha.h,
	    config/arc/tm-arc.h, config/arm/tm-arm.h, config/fr30/tm-fr30.h,
	    config/h8300/tm-h8300.h, config/i386/tm-i386.h,
	    config/i960/tm-i960.h, config/m88k/tm-m88k.h,
	    config/mips/tm-mips.h, config/pa/tm-hppa.h,
	    config/sparc/tm-sparc.h, config/delta/tm-delta.h,
	    config/frv/tm-frv.h (IEEE_FLOAT): For all ports that #define
	    IEEE_FLOAT, make sure they give it the value (1).
