Description of problem:
compile error again on webkit.


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


How reproducible:
autogen.sh ---enable-debug --enable-optimizations --disable-webkit2
make -j6

Steps to Reproduce:
1.download webkit source from http://builds.nightly.webkit.org/files/trunk/src/WebKit-r156422.tar.bz2
2.uncompress it and change directory to WebKit-r156422
3.execute command "./autogen.sh ---enable-debug --enable-optimizations --disable-webkit2"
4.execute command " make -j4"

Actual results:
