[PATCH 0/3] Fix -Wundef warnings in include/ and bfd/

[Andrew Hanson]

This series fixes several -Wundef warnings that appear when building with
extra warning flags enabled. The changes make the conditionals explicit
about whether macros are defined before comparing them.

Notes:
- Only trivial preprocessor guard changes are made.
- No functional behavior changes.
- I left existing style mismatches with .editorconfig as-is.


Andrew Hanson (3):
  include/binary-io.h: guard O_BINARY usage with defined check
  bfd: guard ARCH_SIZE uses to avoid -Wundef
  include/aout/aout64.h: guard ARCH_SIZE with defined()
