# This object lacks a _load_config_used global, so we set
# IMAGE_DLL_CHARACTERISTICS_NO_SEH even though there is an exception handler.
# This is a more secure default. If someone wants to use a CRT without a load
# config and they want to use 32-bit SEH, they will need to provide a
# safeseh-compatible load config.
