[Patch] PR c++/44086

Hi,

This patch fixes PR c++/44086. I've suppressed the check
DECL_INITIAL(x) == NULL_TREE which prevents the
CLASSTYPE_READONLY_FIELDS_NEED_INIT flag to be set. Maybe I miss
something, but I can't find any reasons for checking this here.
Symmetrically, I've done the same for reference, ie for the flag
CLASSTYPE_REF_FIELDS_NEED_INIT.

Tested x86_64-unknown-linux-gnu. OK for trunk ?

gcc/cp/ChangeLog:

2010-05-17  Fabien Chêne  <fabien.chene@gmail.com>
	PR c++/44086
	* class.c (check_field_decls): Remove the check 'DECL_INITIAL (x)
	== NULL_TREE' before setting CLASSTYPE_READONLY_FIELDS_NEED_INIT,
	which was preventing uninitialized const bitfields members to be
	diagnosed. Same for SET_CLASSTYPE_REF_FIELDS_NEED_INIT.
	* cp-tree.h (diagnose_uninitialized_cst_or_ref_member): Change the
	prototype.
