On 3.0.7, the following configure line works:

./configure  --with-apxs=/usr/sbin/apxs --with-config-file=/etc/php3.ini --with-sybase-ct=/opt/sybase

Compiles as (after adding /usr/include/apache to the include directives, why isn't it added automatically??):

gcc -g -O2 -O2 -fpic  -I. -I.   -I/usr/include/apache     -I/opt/sybase/include                         -c language-parser.tab.c -o language-parser.tab.o

.... (no errors reported)

However, in 3.0.10 the exact same configure line (with the same modification added to the Makefile to get the apache headers) results in this:

gcc -g -O2 -O2 -fpic  -I. -I.   -I/usr/include/apache     -I/opt/sybase/include                  -c language-parser.tab.c -o language-parser.tab.o

The reason for the failure seems to be that in 3.0.7, config.status contains these lines:

s%@REGEX_LIB@%regex/libregex.a%g
s%@HSREGEX@%yes%g

while in 3.0.10 they are:

s%@REGEX_LIB@%%g
s%@HSREGEX@%no%g

configure.in has changed from 3.0.7 to 3.0.10 when it tries to find out whether to use apache regex or system regex. In 3.0.10 it relies on apxs to find this out, but it doesn't take into account the situation where apxs might fail due to external reasons not related to regex (like it can't find "bin/httpd"), and therefore the wrong regex will be used. Using --with-system-regex=no on the configure command line makes no difference.

The check mentioned seems to be in configure itself.

Fixed in CVS and 3.0.11
