The use of an Apple sandbox with denied file access permissions into /usr/local exposed that cc1 fails on errors of...
cc1: error: /usr/local/include: Operation not permitted
The commonly suggested solution of using --with-local-prefix= set to something
other than /usr/local is undeirable on darwin because that creates a compiler
which retains library searches in /usr/local/lib despite no longer searching
for headers in /usr/local/include (which makes it suspicable to header/library
mismatches during builds).
The following trivial fix solves the issue by silently ignoring errors from
denied permissions as well as non-existent dirs from the stat (cur->name, &st)
call in remove_dup() of gcc/incpath.c. Okay for gcc trunk and backports to
gcc-5-branch and gcc-6-branch?
