I beg to differ, it works as designed.

As Joerg pointed out, it's the shell that does the expansion, ** is the 
same as one * and only globs one level deep.  It doesn't even find the 
*.h in the working directory.

ls **/*.h is the same as ls */*.h.

It's working as designed, I don't see a "wierd bug", what you want is 
new functionality.

It's the same grep as is being used on Linux, so Linux grep would have 
the same bugs.  What you want to do is more like

find . -type f -name \*.h -exec grep -Hn foo {} \;
