What steps will reproduce the problem?
1. Try running one of the EEPROM examples:

What is the expected output? What do you see instead?

Using Mark Sproul's patched eeprom.h.

This seems to have cropped back up on Windows.  We might have lost the part of 
the ant build.xml script that grabs the custom eeprom.h for Windows.

Never mind, this still to still be fine on Windows...  I think there's 
something else going on with the user who's having trouble:

A very important function like save persistent data doesn't work!
You put the fix in a external website : who is this...how should I trust.
It's very poor and NOT PROFESSIONAL!
