Compiling PHP, are these errors ok? (Linux-Debian-PHP5.3.3)

Question

Are these ok? My config line is this:

./configure  --enable-fastcgi --enable-fpm --with-mcrypt --with-zlib --enable-mbstring --with-openssl --with-mysql --with-mysql-sock --with-gd --with-jpeg-dir=/usr/lib --enable-gd-native-ttf --without-sqlite --disable-pdo --disable-reflection --with-curl --with-mysqli=/usr/bin/mysql_config

And these are the results:

Answer 1

Those test failures are likely to cause serious trouble with your php, if it works at all. For starters, it may have serious trouble talking to MySQL, and issues related to Dates and Times.

Failed tests are almost always a serious problem. Warnings can often be ignored, but ignore unexpected failures at your peril.
