16909 * c-decl.c (finish_enum): Simplify code to determine minimum and
16910 maximum values of the enum, and calculate the type. Remove check
16911 for FUNCTION_DECLs in the values list, which cannot happen. Replace

16913 to the enumeration type. When updating variant types, don't bother
16914 updating the type itself.

16917 when weeding out spurious signed-unsigned warnings. Add new
16918 spurious warning category: if the unsigned quantity is an enum

16921 (build_conditional_expr): Warn here if one alternative is signed
16922 and the other is unsigned.
