Description of problem:
The xmlreader is now enable by default, so is present as a shared extension (build as a .so) and "staticaly" in the apache module.

The new xmlwrite is also enable (staticaly) .


Version-Release number of selected component (if applicable):
5.1.2-2

How reproducible:
Always

Steps to Reproduce:
1. Install php-5.1.2
2. restart httpd
3. read error_log
  

Actual Results:  PHP Warning:  Module 'xmlreader' already loaded in Unknown on line 0

Expected Results:  no warning

Additional info:

I think of adding when building modules (as for xmlreader) :
      --enable-xmlwriter=shared \

Adding, when building the Apache module
      --disable-xmlwriter \
      --disable-xmlreader

And, of course adding the xmlwriter.so to the php-xml rpm.

Work's well for me.
I Hope that's help.
