	 Here are some patches to help libg++ (V1.36 -- the latest
    officially-released version available from labrea) get up and running on
    HP machines.  These patches were made for a g++ configured for
    "hp9k320g", but will probably work for other HP configurations.

	 Problems fixed:

    1. In ctype.h, the ctype classification array is called "_ctype", and
       not "_ctype_".  It is, however, still an array of unsigned char; it
       is NOT an array of short.
---------------
I tried to compile G++/LIBG++ (1.36.1) on HP-UX 6.5, with Darryl's patches.
The ctype patch didn't work out on my system for two reasons:

1. The name is not _ctype, but __ctype on my system.
2. In contrast to other Unix systems the table has the first (superfluous)
element missing, so all (_ctype_+1)'s should be __ctype.

I don't know why this is different on my system, but the following works:
I got the whole system running with the native assembler and loader.
(Just another question: Is there a G++ for the HP9000/800 series?)

// Here's a ctype.h for SunOS-3 and vax 4.3BSD.  
// It will probably work on most BSD derived systems. 
// Just compare it to the C version to verify.
// No big deal, but it will save you some typing.
