Firmware: jcrocholl Marlin latest commits don't compile, had to go back a few months

OK, this commit compiles:

https://github.com/jcrocholl/Marlin/tree/4ffdbcbd4e062ca9a822d49432ce2618d0006a8a

The problem occurs if I enable the LCD Controller support in Configuration.h in later versions: the Arduino IDE shows an error during compilation.

Since I really want the LCD Controller support I had to go looking for an earlier version of Marlin (deltabot branch) that would compile.

Once I got the Marlin code to compile using the Arduino IDE, I wrote the firmware to the Arduino using avrdude and voilà! It works. Next step is to connect the steppers to the RAMPS, the ATX PSU, the heatbed, the hotend, and check that everything works without smoke and flames.
