Patch to add -pedantic -Wno-long-long to cc1plus build

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

This patch adds "-pedantic -Wno-long-long" when building cc1plus to
ensure we don't have any GNUC extensions reintroduced.  It also
deletes a check for GNUC so we can use any ISO C copiler for building
cc1plus.

Tested with --enable-languages=c++ using cc and "make all" which
successfully built cc1plus with the solaris2 ISO C compiler.

I also did a full 3-stage bootstrap and verified that -pedantic
-Wno-long-long got passed to files in the cp/ dir.

Ok for mainline?

		Thanks,

	* Make-lang.in (cp-warn): Add $(STRICT_WARN).
	* cp-tree.h: Don't insist on having GNUC.
