Thanks for that.  mozilla-1.3.1,2 compiles and installs successfully.

Unfortunately, it doesn't run.  I get an unaligned access report,
followed by a segmentation violation:
pid 49966 (mozilla-bin): unaligned access: va=0x160bbb2df pc=0x160b9db2c ra=0x16200e8ac op=ldq

(gdb) where
#0  0x160b9eaa000 in ?? ()
#1  0x160b9db30 in nsPref::GetDefaultIntPref(char const*, int*) ()
   from /usr/X11R6/lib/mozilla/components/libpref.so
#2  0x160b9db30 in nsPref::GetDefaultIntPref(char const*, int*) ()
   from /usr/X11R6/lib/mozilla/components/libpref.so
Error accessing memory address 0x10: Bad address.
(gdb) 

Suspiciously, the address looks like it is shifted 8-bits left, which
is consistent with the unaligned access being one byte below an
aligned address.  This looks like an out-by-one error somewhere.  I'll
try re-compiling with the defaults (rather than for ev56) and see if
this is just a gcc bug (as I suspect).

BTW, has anyone else noted problems debugging processes when there is
other system activity?  (5.1-RELEASE on a 4-CPU AS4100)  On several
occasions I've had gdb go to sleep - it won't respond to QUIT, STOP or
INTR from the keyboard but it can be killed from another process.  When
it gets into this state, ps shows:
