Upon building PHP4.x.x (including RC1/RC2/CVS) on Apache 2.0.x (currently 2.0.35) The make fails on this:
sapi_apache.c: In function `apache_php_module_main':
sapi_apache.c:81: `NOT_FOUND' undeclared (first use in this function)
sapi_apache.c:81: (Each undeclared identifier is reported only once
sapi_apache.c:81: for each function it appears in.)

Apache was configured in the following :
./configure --prefix=/www --enable-so --enable-ssl
make 
make insall
PHP 4.x was configured in the following:
./configure --with-mysql --with-apxs=/www/bin/apxs
make (failed)

RH7.296 (7.3beta) Kernel 2.4.18grsec1.94 / GCC3.0.4 / Apache 2.0.35 mod ssl/so

Im aware of known issues with 4.2.xRC1/RC2 with Apache 2.0.x
This is reproducable on several systems of mine 
RH7.1 Kernel 2.4.16 / GCC2.96 / Apache 2.0.35
RH7.0 Kernel 2.2.23 / GCC2.95 / Apache 2.0.34
SuSE 7.3 Kernel 2.4.7 (SuSE Optimizations left in place) GCC3.0.4 / Apache 2.0.34

Any help on this is appreciated if it is merely a(n) error on my part. I do have a succesfull build on:
RH7.2 Kernel 2.4.16grsec1.93 / GCC3.0.4 / Apache 1.3.23/24

Thanks.
