buildfarm member koi, having recently been rescued from git purgatory,
is failing like this:
configure: using CFLAGS=-O -Kinline
configure: using CPPFLAGS= -I/usr/local/include/libxml2 -I/usr/local/include
configure: using LDFLAGS= -L/usr/local/lib -L/usr/local/lib
preparing build tree... UX:find: ERROR: Illegal option -- -path
UX:find: TO FIX: Usage: find [path-list] [predicate-list]
UX:ln: ERROR: Cannot create /home/ohp/pgfarmbuild/HEAD/pgsql.10464//config/Makefile: No such file or directory
configure: error: failed
which indicates it can't cope with your recent patch to prep_buildtree.
I was afraid that might be a problem. Can we please stick to the
find(1) options defined by the Single Unix Spec?
