To the members of the GNU project maintaining @file{gdb}:
 
Note that all tab character in this file are lost because of the
mail processing software.
 
I am Owen Le Blanc of the Ocmputing Centre at the University of
Manchester, ZLSIIAL@CMS.MCC.AC.UK on the Janet network.  I have
been maintaining versions of GNU CC and other GNU software on 10
large HP clusters with 86 processors, nearly all running HP-UX at
level 6.5.
 
I compiled @file{gdb} version 3.5 using the GNU C compiler in its
non-native version, that is, using the GNU assembler and loader
(tm.h = tm-hp9k320g.h).
 
The following change is required in readline.c because when
editing is on, the prompt (gdb) does not appear until after the
prompted input has been read:

Why isn't history expansion on by default?

It is very convenient for those of us who are not using standard Unix
@file{ar} and @file{ranlib} that @file{gdb/readline/Makefile} includes
variables @var{AR} and @var{RANLIB}.  Unfortunately @file{gdb/Makefile}
does not support these variables.
 
Make clean is altered to delete @file{y.*} and @file{copying.c}.
The latter file should remain in the distribution only if local
versions of @code{awk} fail.
 
The remaining changes in the Makefile are introduced to make gdb use
gcc's @code{__builtin_alloca}.  Of course it would be better if all
files in GNU software using @code{alloca} included the test
 
     #ifdef __GNUC__
     #define alloca __builtin_alloca
     #endif
 
This would make all special handling of @code{alloca} unnecessary.

The changes to @file{config.gdb} below introduce the definitions of
ranlib and ar, and incidentally change &var{GLOBAL_CFLAGS} to optimise
and to define @code{__builtin_alloca}.

I hope this information will be of use to others, and that I
haven't spent too much time on my personal bugbears!
