I tested on the following x86 boxes:
Win32 VC6/sp3 -Ox (maximum optimization)
FreeBSD-3.3 gcc-2.7.2.3 -O2
RedHat-6.1 egcs-2.91.66 -O3
2.2.12-20smp libc-2.1.2
and on SS20 with
Solaris-2.6 egcs-2.91.60 -O
On all these systems I get identical results. `slides' happily
converges in two runs. `user' converges in 6 runs.
For `user' on x86 boxes after the 5th run I get:
gra_summ:8:1: 23.6c object too high for 23.6c space; @Scale inserted
all:14:1: unresolved cross reference @Runner&&following
all:14:1: unresolved cross reference @Runner&&following
where the first one is really: 23.57848c object too high for 23.57672c.
Diffing xref db from 5th run produced on FreeBSD and RedHat shows no diffs.
After the 6th run document converges. Diffing all the three xref dbs
and the xref db from Sparc shows no diffs (well, for win32 it does
show diffs, but those are due to CRLF line ends). Ediffing postscript
output shows only occasional minor deviations in numbers. Ediffing
with Sparc output shows more deviations but nothing significant.
PS: Are you sure `user' converged in 4 runs? Does the 5th run produce
identical results? 4th run on Sparc produces no warnings, but it
has not converged yet - save lout.li *.ld and *.ps run again and
diff to see.
PPS: Emacs' ediff-files (under X or Win32) is really nice way to check
where PostScript ouputs differ as ediff will refine differences to
word granularity - which is much easier than hunting for 7192 vs
7193 in diff output.
PPPS: It might be a good idea to strut running headers vertically , so
that the height of headers does not depend on the running title
(e.g. ascenders, descenders) - though I haven't tried it.
