Intel IPP build warnings under Linux

My company is using Intel IPP, when compiling under Ubuntu the console is flooded by warnings of this form:

include/ippcp.h:73:0: warning: ignoring #pragma warning [-Wunknown-pragmas]
#pragma warning(push)

Our license doesn't allow us to modify the IPP headers to fix this line, we tried wrapping all includes in a #pragma diagnostic, but unfortunately this particular warning can't be ignored in this way under GCC.
IMO this is a bug, can someone please point me to the appropriate place where I can report it?

Thanks, Ben
