Argh, this is what I had done recently but didn't manage to submit yet.
(I told in a mail that I had done programs/ and tools/)

Imperfect - it should be static const char * const ignored_fstypes[]
since otherwise the ignored_fstypes pointer is still non-const (objdump -x)
which it doesn't need to be (may mark more memory pages as read-write than
necessary).

Sure, your objective was to fix all strict compiler warnings which that patch
probably did successfully, but why not go that extra mile...
