Peter,
I had the same idea last night. I modified my PowerPC cross-compiler
"port" to produce an Alpha version. This is based on the lang/gcc295
port so it contains the FreeBSD patches for things like -Wformat. For
sake of example, I only worried about the compiler and not linking
since that would require compiling or downloading the libs for an
Alpha.
# uname -m
i386
# cvs update -r1.5 chkgrp.c
P chkgrp.c
# make CC=alpha-gcc chkgrp.o
alpha-gcc -O -pipe -W -Wall -Wstrict-prototypes
-Wmissing-prototypes -Wpointer-arith -Wno-uninitialized -Werror
-Wreturn-type -Wcast-qual -Wwrite-strings -Wswitch -Wshadow -c
chkgrp.c

This could help prevent breakage to buildworld on other platforms
but, of course, does not prevent runtime errors from creeping in.
If there is interest in this, I could see about getting this into
ports (after a little testing and tweaking).
