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. It seems that each includer of packfile.h includes the definition of the enum before including packfile.h.
