It seems to me that there is a precedence for -W type tests to start 
with a capital letter, as opposed to a lowercase letter:

$ cd gcc.dg
$ ls W[a-z]* |wc
    280     280    5816

Do you think it would perhaps be reasonable to rename all of them to 
uppercase?  You could take -Wvla-[1-7].c and I can take the subsequent ones?
