Yes.

Here is the change I made when I encountered this problem.  Note that
you should modify gcc's private copy of the header files, not the one
in /usr/include.

I have no idea what the purpose of this statement is supposed to be.
It looks somewhat pointless to me.  But then again, this is HP-UX...
