# The rest is just x-i386v4.
# The svr4 reference port for the i386 contains an alloca.o routine
# in /usr/ucblib/libucb.a, but we can't just try to get that by
# setting CLIB to /usr/ucblib/libucb.a because (unfortunately)
# there are a lot of other routines in libucb.a which are supposed
# to be the Berkeley versions of library routines normally found in
# libc.a and many of these Berkeley versions are badly broken. Thus,
# if we try to link programs with libucb.a before libc.a, those
# programs tend to crash. To avoid this, we link with libc.a *before*
# linking with libucb.a.
# Some versions of SVR4 have an alloca in /usr/ucblib/libucb.a, and if we are
# careful to link that in after libc we can use it, but since newer versions of
# SVR4 are dropping libucb, it is better to just use the portable C version for
# bootstrapping. Do this by defining ALLOCA.
