Adding "using namespace..." causes compilation error [expected '=', ',', ';', 'asm' or...] in xcode 4

This is strange, whenever I add "using namespace ..." to a header file it craps out 

 error: expected '=', ',', ';', 'asm' or '__attribute__' before 'namespace'

on me.

I remove it, and try to use namespace operator ::, like cv (for OpenCV) it says 

error: expected ')' before '<' token

My header file has .hpp extension, and implementation file has .mm. It looks like xcode 4 is trying to compile it as a traditional C file. Is that right?

How do I fix this?

You can change your source file type in Utilities -> File Inspector panel (⌘⌥+1). Check "Identity and type" section. It has "File type" drop down there. Check the appropriate file type there and you should be good.
