# moussh uses labeled control structure.  On my systems, I've put this
# into gcc (it's fairly straightforward).  While a full implementation
# of labeled control structure really does need to be in the compiler,
# moussh doesn't use the full power of it, and it's feasible to convert
# the limited subset used to standard C (or at least gcc) with purely
# textual hacks, without needing a full codewalker.  That's what lcs-cvt
# is for.  The test here is basically testing "is this one of Mouse's
# systems"; this is not the best test possible, but it's probably good
# enough for the purpose at hand.  (Basically, if it's 1.4T and
# /local/bin/mcsh exists, I assume it's mine.)  If it's not my system,
# a .c.o rule is added which runs lcs-cvt in between the preprocessor
# and the compielr proper.
