I've had to "fix" 5 different .h files with v1.1.1. The problem is that
these files aren't self contained, i.e. they don't #include other files
they depend on. At the very least these are documentation bugs that don't
specify all the files you have to #include to use a particular class - but
they are really bugs in the .h files. (Quality control isn't what it used
to be.)

I'll re-test my build and make sure I'm using un-fixed versions - I
probably just need to #include additional files in the handwritten code.
