Small patch to get bash 2.05b compiling on HP/UX 11.00

[Petter Reinholdtsen]

Here is a small patch to get bash 2.05b to compile on HP/UX 11.00
using the bundeled K/R C compiler.  The compiler is not very good, but
it is the one I have access to at the moment.

 - Suffix #UL is not supported.  Use ((unsigned long)(#)) instead.

 - It failes with 'unexpected character "}"' (or something similar if
   a goto target is followed by '}'.  Adding 'return;' fixed the
   problem.

 - The character constant '\a' is unknown.  Using ASCII #7 instead.

 - Keyword 'const' is not handled.  Make sure "config.h" is included
   to get the replacement define.
