[PATCH] c++: Failure to delay noexcept parsing with ptr-operator [PR100752]

[Marek Polacek <polacek@redhat.com>]

We weren't passing 'flags' to the recursive call to cp_parser_declarator
in the ptr-operator case and as an effect, delayed parsing of noexcept
didn't work as advertised.  The following change passes more than just
CP_PARSER_FLAGS_DELAY_NOEXCEPT but that doesn't seem to break anything.

I'm not passing member_p because I don't need it and because it breaks
a few tests.

Bootstrapped/regtested on x86_64-pc-linux-gnu, ok for trunk/branches?

	PR c++/100752

gcc/cp/ChangeLog:

	* parser.c (cp_parser_declarator): Pass flags down to
	cp_parser_declarator.

gcc/testsuite/ChangeLog:

	* g++.dg/cpp0x/noexcept69.C: New test.
