Hey Marc,

here are my lines to configure CGAL


 export 
CGAL_CMAKE_COMMON_FLAGS="-DCGAL_CXX_FLAGS:STRING=-D__USE_ISOC99=1 
-DCGAL_CXX_FLAGS_RELEASE:STRING=-D__USE_ISOC99=1
      -DBoost_INCLUDE_DIR=$EXACUS_BOOST 
-DBoost_THREAD_LIBRARY=$EXACUS_BOOST/stage/lib/libboost_thread-mt-d.dylib
      -DGMP_INCLUDE_DIR=$EXACUS_GMP/include/ 
-DGMP_LIBRARIES=$EXACUS_GMP/lib/libgmp.dylib
      -DGMPXX_INCLUDE_DIR=$EXACUS_GMP/include/ 
-DGMPXX_LIBRARIES=$EXACUS_GMP/lib/libgmpxx.dylib
      -DMPFR_INCLUDE_DIR=$EXACUS_MPFR/include/ 
-DMPFR_LIBRARIES=$EXACUS_MPFR/lib/libmpfr.dylib
      -DWITH_LEDA=OFF
      -DWITH_CGAL_Qt3=OFF
      -DWITH_CGAL_Qt4=ON
      -DWITH_CGAL_Core=ON -DWITH_CGAL_ImageIO=ON -DWITH_CGAL_PDB=ON
      -DWITH_examples=OFF -DWITH_demos=OFF
      -DCMAKE_VERBOSE_MAKEFILE=ON"

(with Variables properly set)

cmake -DCMAKE_BUILD_TYPE="Debug" $CGAL_CMAKE_COMMON_FLAGS 
-DCGAL_PACKAGES_FILE=$CGAL_CMAKE_DIR/packages-to-include.txt 
$CGAL_INSTALLATION_SOURCE_DIR

The second is a "hotbuild".

But most interesting for you might be

-DCGAL_CXX_FLAGS:STRING=-D__USE_ISOC99=1 
-DCGAL_CXX_FLAGS_RELEASE:STRING=-D__USE_ISOC99=1
