Thanks for a terrific explanation of the -DEAPI situation. So then, when I still get the Plain Apache error after compiling after adding -DEAPI to my C compiler flags...it doesn't necessarily mean that it recognizes I am including the mod_so.c (so I can add the jserv module in httpd.conf) and that it is OK because using -DEPAI will keep me safe? I woud suspect I still have something wrong, correct?
Ultimately I am expecting that I do not see the warning when launching Apache. Is that what I should suspect? Because at the moment, I am still seeing it.
