The only thing that's really important is that PACKAGE isn't NULL,
because it's just a workaround for this brilliant gem from bfd.h:
35 /* PR 14072: Ensure that config.h is included first. */
36 #if !defined PACKAGE && !defined PACKAGE_VERSION
37 #error config.h must be included before this header
38 #endif
So if you feel strongly about it, feel free to post a patch that just
sets PACKAGE to 1. This would avoid all possible ambiguity.
