The old cpp version generated: __db_version 5

Configure then correctly picked up the version, since it greps for "__db_version".

The new output: __db_version 5

Grepping no longer works and configure fails.

Running cpp with -P (inhibit linemarkers generation) fixes this when using gcc 5. Behavior with older versions of gcc is not changed.
