Icc does not fully support standards and does not define isfinite(), isnan().

My system:
Gentoo x86_64 linux
icc (ICC) 11.1 20100414

Also, i do not know version of webkit(so it probably is wrong), i only know the version of Qt.

Comments from Olivier (our compiler guy):
<ogoffart> benjaminp: mmh, i remember i had those errors
<ogoffart> benjaminp: that is because the version of the libstdc++ he is using is not compatible with the icc version i think
<ogoffart> "Icc does not fully support standards and does not define isfinite(), isnan()."  <- this sentence is wrong
<ogoffart> ICC defines in its requirement a version of libstdc++ he is compatible with
<ogoffart> anyway, ICC 11 is too old, we reported many other issues, ICC 12 should be used
