If you tested this version thoroughly than this is fine for me. Did you 
build all RTEMS targets which currently use GCC 6 with this version and 
can you provide the RSB patches? If yes, then please use the versions 
specified by GCC contrib/download_prerequisites for the support libraries.

A new GCC version probably means new warnings to fix.

We should manage the GCC selection better in the future. GCC 6 received 
considerable more testing and regression fixes than GCC 7.1 which is 
only two weeks old.
