Actually, I don't think there is anything stopping -DAP_DEBUG from
coming through from the httpd config. The change that was made
(r357052) just stopped mod_perl from adding that itself when
MP_MAINTAINER is specified.
But maybe we do need to filter out -DAP_DEBUG?
Or else stop using ap_strchr() and just use strchr() directly?
Could you try the latter, since it seems like an easy fix? -- Change
the one instance of ap_strchr() in xs/Apache2/Module/Apache2__Module.h
to be strchr() instead and then rebuild. Does that make the problem go
away?
