Created attachment 38542 [details] modules/mappers/config9.m4: Add 'server' directory to include path if mod_rewrite is enabled. mod_rewrite requires test_char.h. Hence add /server directory to the include path for Linux systems.
Thanks for the patch. I guess we did not notice, because we always build mod_log_forensic as well during our tests which already adds server to the include path. Fixed in r1909241. For Windows this was already fixed in r1908937 / r1909061.
Proposed for backport as r1909276
