I want to change crt0.o to initialize some debugging code before
calling the user's main().  I've looked at the existing __start using
dbx, and I've duplicated the instruction sequence, but when I try `nm
/usr/lib/crt0.o' I still see some things I don't understand.  (For
example, how much of the moncontrol stuff is necessary?) We have
Ultrix sources but our sysadmin people have been unable to find crt0.s
for me.  Can anyone point me to a copy of crt0.s for the MIPS, or tell
me what manual explains what this code is supposed to do?
