Bug 539636

Description of problem:
g++ stopped a long time on compilation of Engrid software. The entire compilation process takes about 2 hours instead of only few minutes

Version-Release number of selected component (if applicable):
Current version of gcc-c++ on Fedora 12
Using built-in specs.
Target: i686-redhat-linux
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-languages=c,c++,objc,obj-c++,java,fortran,ada --enable-java-awt=gtk --disable-dssi --enable-plugin --with-java-home=/usr/lib/jvm/java-1.5.0-gcj-1.5.0.0/jre --enable-libgcj-multifile --enable-java-maintainer-mode --with-ecj-jar=/usr/share/java/eclipse-ecj.jar --disable-libjava-multilib --with-ppl --with-cloog --with-tune=generic --with-arch=i686 --build=i686-redhat-linux
Thread model: posix
gcc version 4.4.2 20091027 (Red Hat 4.4.2-7) (GCC) 

How reproducible:
Download the Engrid sources and compile it. Have to install vtk-devel, vtk-qt, qt-devel, qt-gui

Steps to Reproduce:
1.
git clone git://78.140.120.226/git/engrid.git
cd engrid
git checkout -b release origin/release
2.
export VTKLIBDIR=/usr/lib/
export VTKINCDIR=/usr/include/vtk
3.
Enter in src directory
./scripts/build-nglib.sh  (to compile netgen-mesher)
4.
qmake
make

  
Actual results:
Make command stopped on this warning too many times

Expected results:
Make command compiles the software in few minutes (on Intel(R) Pentium(R) Dual  CPU  T2390  @ 1.86GHz)
