I think there is a slight problem that broke the build with non-GNU bourne shells. We have a build failure on our solaris 2.8 machine, for instance. Here is what I think the problem is: > + # GCC supports -Wuninitialized only with -O or -On, n != 0. > + if test x${CFLAGS+set} == xset; then ^^ I think the "==" should be "=", no? That's what "man test" documents. But I've never been a shell guru... -- Joel
