compile ROOT with icpc :: cannot open source file "iostream.h"

Hi! I try to compile root with the intel compiler : adrian_at_sevdell : v5-28 $ icpc -v
icpc version 12.1.0 (gcc version 4.5.0 compatibility)

on fedora 15 x86_64 and i have the following error: adrian_at_sevdell : v5-28 $ make
bin/rmkdepend -R -fcint/cint/src/dict/libstrm.d -Y -w 1000 -- -pipe -m64

  #include <iostream.h>

                       ^

compilation aborted for cint/cint/src/dict/libstrm.cxx (code 4) make: *** [cint/cint/src/dict/libstrm.o] Error 4

this is something strange as if i search for iostream.h i dont have it in system (nor is it found in repos) but normal compilation with gcc works.

Does anyone have any idea about this?
Thanks!
