Just figured out it was the "-mstrict-align" switch; removing it
does what I want, and in this case it also makes the asm output (and
I assume the resulting object code too) roughly 30% smaller.  Is there
a good reason for keeping it?  Is it required for internal EPICS
reasons, and if so can we at least turn it off in user code, e.g.
device support?  Or is it perhaps a local SLAC thing...
