[TYPO3-install] What should be compiled into PHP for version 4.2?

[Michael Davidson]

Installing Typo3 4.2 and want to confirm what should be compiled into PHP5
for Typo3 to run smoothly. Here is what I have and all seems to be working
ok. What can be safely removed?

(The first two are not in the requirements page and should be)

XML Parser Functions
Session Handling Functions
MySQL database support (change depending upon your desired database)

Not certain if these are needed...but installed anyway 

SPL Functions 
Zlib Compression Functions 
GD 2.x library support (seems like this is needed) 
PCRE Regular Expression Functions (Perl-Compatible) 
MySQLI MySQL Improved Extension 
CURL support 
MBSTRING Multibyte String Functions 
SimpleXML Functions

Can anyone confirm which are not needed?
