[TYPO3-core] RFC #15075: feature: make a pre-check for required php-extensions

Hi,

Yes, I read this thread too.

That's OK.

> - zlib

mysql is not necessary as such but a database driver is. I'm OK for 
having the test for mysql as long as there is a pretty way of overriding 
this check with an "enhanced" one if DBAL is active, that's all what I'm 
asking.

Let's see what others say regarding this patch and I'll later see how to 
make it "compatible" with DBAL without having to XCLASS it. We'll find 
some easy and good looking solution!
