Extended Description

Running Memtest86+ through the Clang static analyzer the warning below is shown.

$ clang-4.0 --version
clang version 4.0.0-+rc1-1 (tags/RELEASE_400/rc1)
Target: i686-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
$ scan-build-4.0 -o /dev/shm/html make CC=clang-4.0
[…]
warning: Path diagnostic report is not generated. Current output format does not support diagnostics that cross file boundaries. Refer to --analyzer-output for valid output formats
[…]

Unfortunately, that switch does not exist.

$ scan-build-4.0 --analyzer-output
scan-build: unrecognized option '--analyzer-output'

It’d be great if the warning could be updated.
