* lib/target_suports.exp
(check_effective_target_has_w_floating_suffix): New procedure.
(check_effective_target_has_q_floating_suffix): Ditto.
* g++.dg/cpp0x/gnu_fext-numeric-literals.C: Add dg-error directive
for unsupported non-standard suffix on floating constant.
* g++.dg/cpp0x/std_fext-numeric-literals.C: Ditto.
Attached patch was re-tested on alphaev68-linux-gnu and
x86_64-linux-gnu and committed to mainline SVN.
Uros.
