Yes, they are fixed in master on GitHub. Note that there are quite a few 
changes since 1.4 – I can’t promise that master has ABI compatibility with the 
last official 1.4 release. But if you compile the new sources using the old 
headers (or diff and merge manually) I don’t think there will be an issue on 
that front.
