   1 # Some versions of SVR4 have an alloca in /usr/ucblib/libucb.a, and if we are
   2 # careful to link that in after libc we can use it, but since newer versions of
   3 # SVR4 are dropping libucb, it is better to just use the portable C version for
   4 # bootstrapping.  Do this by defining ALLOCA.
