[gcc patch] Move ENUM_BITFIELD to ansidecl.h


Hi,

[patch] ENUM_BITFIELD broke GDB
http://sourceware.org/ml/binutils/2011-04/msg00333.html

ENUM_BITFIELD has been now defined in bfdlink.h which is included only in some
GDB sources.  There would be needed some
	#ifndef ENUM_BITFIELD
	#define ENUM_BITFIELD
but I find it fragile.

Is approved its unification into ansidecl.h across gcc/binutils/gdb?

GCC still builds with the patch.


Thanks,
Jan
