Hi again- now that I know it's the "-mstrict-align" that's causing the
byte operations, I still have 2 questions...

1) I see that this switch is provided by EPICS/base/config/CONFIG.Vx.mv2400:

	ARCH_DEP_CFLAGS = -mcpu=604 --no-builtin -mstrict-align -mlongcall

   What's the proper way to override this in a local work area config directory?

2) What switch (or lack of) does this compiler need to turn this feature off?
   A quick naive test of re-running just the gmake-generated ccpcc command without
   the mstrict switch makes the assembly phase barf, though I'm easily convinced
   that this may be due to the lack of proper environment caused by running it
   in isolation:

		as: error: unknown option 'p'
		as: error: unknown option 'p'
		usage: as [-V] [-Q{y,n}] [-f[O][if]#] [-q] [-s]
		          [-S] [-K {pic,PIC}] [-o objfile] [-L] [-T]
		          [-P [[-Ipath] [-Dname] [-Dname=def] [-Uname]]...]
		          [-m [-Ym,path]] [-n] [-ul] [-xF] [-xarch=v7] [-xarch=v8] [-xarch=v8a] [-xarch=v8plus] [-xarch=v8plusa] [-xar\
ch=v8plusb]  [-xarch=v9] [-xarch=v9a] [-xarch=v9b]  [-xcode={pic13,pic32}] file.s...

thanks,
Mike
