Within the `__GXX_ABI_VERSION` block this should always be defined, guard against unexpected defines and make the error obvious.

Marcus D. Hanwell	b72c42d489	Include GXX_ABI and USE_CXX in the identifier Further constrain to GXX_ABI 1002 or greater and less than 2000, hopefully future proof by summarizing that as `1` along with CXX11 on or off.	2024-11-20 16:37:16 -05:00
