AP_DEBUG is pure evil if it's making its way into the builds of APR modules.It
takes strchr and the like and REPLACES THOSE with ap_strchr. The onlyway round
this is to use apr_ stuff instead.

Hi Steve
I modified xs/Apache2/Module/Apache2__Module.h and replaced ap_strchr with
strchr before recompiling. I still got the same error message after that.
I re-compiled apache without enabling the maintainer mode:

Adding "--enable-maintainer-mode" and re-compliling apache, I could get "make
