+After editing the files you will have to run the build script again to ensure that flext is built.
After successfully building everything, you can install flext with (under Windows)
build pd msvc install
or (under unix)
bash build.sh pd gcc install
+
You will probably have to have superuser rights in order to install things
into the default location.
(try "sudo" or "su -c" prefixes, or log in as root)

- fixing uninitialized pointer (first inlet pointer)
- added message bundle functionality (to send more messages over the thread boundary to arrive at the same logical time)
- fixed dangerous spot (also memory leak) with message queuing
+- fixed buggy freeing of memory for AtomListStatic
0.5.0:
- fixes for 64 bit builds (size_t is integer type of pointer size)
