When compiling under Apple LLVM version 9.1.0 (clang-902.0.39.2) with
"make DEVELOPER=1 DEVOPTS=pedantic", the compiler says
error: redeclaration of already-defined enum 'object_type' is a GNU
extension [-Werror,-Wgnu-redeclared-enum]
According to https://en.cppreference.com/w/c/language/declarations
(section "Redeclaration"), a repeated declaration after the definition
is only legal for structs and unions, but not for enums.
Drop the belated declaration of enum object_type and include cache.h
instead to make sure the enum is defined.
