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
