ddd-3.3.10 HP-UX 11.11 with aCC

[Paul Ackersviller]

You said you'd like to hear about this, so here goes.  Configuring with
CC=aCC CXXFLAGS=-AA worked fine, but the compile failed early with:

        Error 24: "/usr/include/strings.h", line 54 # '<type name>' expected 
instead of '0'.
         extern void bzero(void *, size_t);
                     ^^^^^
        Error 497: "/usr/include/strings.h", line 54 # There can be only one 
function 'memset'
    with "C" linkage; previous declaration was at ["/usr/include/string.h", 
line 204].
         extern void bzero(void *, size_t);
                     ^^^^^

This can be alleviated by hacking ddd/config.h after configure, like so:
--- ddd/config.h        2007/04/20 15:08:11     1.1
+++ ddd/config.h        2007/04/20 16:35:00

 /* Define to 1 if you have the <strings.h> header file. */

-
+#undef HAVE_STRINGS_H  /* aCC doesn't like both this and next */
 /* Define to 1 if you have the <string.h> header file. */
 #define HAVE_STRING_H 1

An even easier way is to fake out the header file to think it's already
been used by CPPFLAGS=-D_STRINGS_INCLUDED (or there may be a better
macro to use to specify certain standards-compliancy, I haven't tried
much else).  After one of these, ddd compiles and links fine, and I haven't
encountered any runtime problems yet, but haven't tested extensively.

A couple of other things to note:
1. 32-bit compiles seem to require the flag +Onolimit, which requires
   optimization level at least +O2.
2. 64-bit compiles don't have the above problem, however the HP-UX link
   has has the 32-bit static /usr/lib/libXm.a hard-coded.  Needless to
   say this needs changing, and I have no apparent problems with the
   shared 64-bit Motif library.

Is the static 32-bit Motif library required for current HP-UX version,
or does that really only apply to older ones?
