We also did this on our HPs since we also have Suns and a Pyramid.
Unfortunately some utilities didn't grok long names. The specific
instance I uncovered is that ar only handles 14 char filenames.

Example:

% cat main.c
main ()
{
  func ();
}
% cat longlonglonglong.c
#include <stdio.h>

func ()
{
  printf ("one\n");
}

% cc -c longlonglonglong.c
% cc -c main.c
% ar rv libnew.a longlonglonglong.o
a - longlonglonglong.o
ar: creating libnew.a
% cc -o main main.o libnew.a
% ./main
one
% ar vt libnew.a
rw-r--r--   214/    20    160 Oct 12 17:00 1989 longlonglonglo
% vi longlonglonglong.c
....
% cat longlonglonglong.c
#include <stdio.h>

func ()
{
  printf ("two\n");
}
% cc -c longlonglonglong.c
% ar ruv libnew.a longlonglonglong.o
a - longlonglonglong.o
% ar tv libnew.a
rw-r--r--   214/    20    160 Oct 12 17:00 1989 longlonglonglo
rw-r--r--   214/    20    160 Oct 12 17:06 1989 longlonglonglo
% cc -o main main.o libnew.a
% ./main
one
%

Nice, huh? Not only do you get the wrong module, but the library size
would grow indefinately.

[Hey HP: this is still broken under 6.5. Will it be fixed for 7.0?]

After this little gotcha I didn't bother testing RCS & SCCS, but I would
bet they break also.
