OK.  I don't have a HP/UX machine here to test with, so I was guessing a
little.  This time I put the "inline pow(double, int)" into my math.h so
I can duplicate the error.

I discovered that fdlibm.h does the same thing, wrapping the includes
into a extern "C" block.  Both files are patched below.  This should
work on a fresh libgcj tree:
