You need to use the ANSI flags for cc (-Aa).  Alternatively you could use
the ansic compiler that typically is in HPUX under /opt/ansic.

You can accomplish this with CFLAGS="-Aa" configure.

I use gcc to compile ruby for HPUX 11 (32 and 64 bit).  configure gets a
decent set of flags by default.  HPUX 10 is pretty old so that's probably
why configuring with cc doesn't work out of the box.
