The xterm in question has been internationalized. However there appears
to be an unanticipated side effect caused by both crt0.o and Xt calling
setlocale, or it might be the LC_CTYPE=iso_8859_1, which *is* bogus for 
FreeBSD. If the user wants to set LC_CTYPE, it should be to a valid
locale name for the system. 

(The LC_CTYPE=iso_8859_1 is a SunOS thing that was apparently copied 
from an example in a FAQ about how to get 8859-1 on SunOS.)

Xedit in the R6 contrib has also been internationalized. Since it does 
not dump core on FreeBSD, with or without ENABLE_STARTUP_LOCALE, with 
or without the bogus LC_CTYPE, and the stack trace showed that it dumped
core in xterm code, the problem may be that xterm assumes the startup
locale will be C.
