Changes to eSpeak to support building on a POSIX system by running make.
This does the following things:
1/ compile the libespeak library;
2/ compile the speak and espeak command-line applications;
3/ compile the espeakedit application;
4/ compile the voice data, creating an espeak-data directory.
This allows you to run:
make && sudo make install
and end up with a working espeak application.
This branch also contains some bug fixes and improvements that get
sent back upstream.
