I did a

    ./configure --with-apxs --with-mysql

and then a

    make install

All seems fine, except when I did a apachectl start, 
apache comlains of the following:

[Fri Dec 29 07:27:43 2000] [warn] Loaded DSO /
System/Library/Apache/Modules/libphp4.so uses plain 
Apache 1.3 API, this module might crash under EAPI! 
(please recompile it with -DEAPI)
/usr/sbin/apachectl start: httpd started

However, the warning is not produced if I take the '--
with-mysql' out of the ./configure command line.

I then looked up EAPI in the bugs database, and found 
#3918 where the use of

    '--enable-rule=EAPI'

was mentioned.  So I did the same, and found as the 
reporter did, that -DEAPI line was not produced while 
compiling, which resulted in the same warning as 
before.  I must say, though, that ./configure --help did 
not reveal that particular option.

Then bug #3583 revealed that a manual hack of the 
configure script worked for the reporter.  So I appended 
-DEAPI to CPPFLAGS for the darwin platform, and 
verified that the -DEAPI is being included in all compile 
(and link) lines.  However, the same warning still 
occurs whenever I do a

    apachectl start

Please advise.  Thanks!
