    Fix VS 2015 build failure.
    
    Thanks to Pavel Kryukov's CI for pointing this out: VS 2015 doesn't
    support C99 hex floating-point literals.
    
    (VS 2017 does, and in general we're treating this as a C99-permitted
    code base these days. So I was tempted to just increase the minimum
    required compiler version and leave this code as it is. But since the
    use of that particular floating literal was so totally frivolous and
    unnecessary, I think I'll leave that for another day when it's more
    important!)

    DSA key gen: start from 2 when looking for g.
    
    Having just written a comment about how it was almost inconceivably
    improbable that you _wouldn't_ be successful in finding a suitable g
    on the very first number you tried, I couldn't help noticing that in
    fact my very next DSA key generation test had to try twice. Had I made
    a mistake in my probability theory?
    
    No, it turns out: I find g by raising consecutive numbers to the power
    (p-1)/q and looking to see if they're not 1, but I start with 1
    itself, which along with -1 is the only number that _can't_ work!
    
    Save a bit of pointless effort and iterate up from 2 instead.
