On this point, when FX removed the 2>/dev/null redirection there were no errors
shown, and several people have confirmed that when the error happens the
symlink *does* exist.
What I haven't seen any confirmation of is whether the symlink actually points
to the right file:

Yet another one:
In file included from

^~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
make[5]: *** [x86_64-apple-darwin17.0.0/bits/stdc++.h.gch/O2g.gch] Error 1
Yet when make aborts, the file
x86_64-apple-darwin17.0.0/libstdc++-v3/include/bits/stl_construct.h is present.
Can somebody confirm the links are not only present, but point to the relevant
file in the source tree?
