time for 1.5.11?

[Christopher Faylor]

Hmm.  I really botched 1.5.10.  First I ran the test suite on an older
version of cygwin and released a non-working DLL, then I released a
version of the DLL which identified itself as 1.5.9.  Now, I just
realized that all of the snapshots since 1.5.10 have identified
themselves as...  1.5.10.  I have no idea how I managed to do that.
I see the CVS logs where I did it but I must have gotten the branching
wrong for 1.5.10, too.  Chalk up another mistake.

Anyway, on to the future...  Would it make sense to release a 1.5.11?
Do you think we've hit all of the fallout from the path reorg/speedup?

The minimal list of changes is below.  I probably need more words from
Pierre and Corinna, as usual.
