ARDUINO 1.5.4 : compiling problem using a RTC library

Using Arduino Programming Questions
1

Hi,

I have been using (Under Arduino 1.03 IDE on winXP) a Mega, and a RTC breakout board.

The RTC chip is the DS3231, and I have been using an interesting library for it, that makes unix time available on an arduino, including synchronization of the milli function of the arduino, with the RTC.
the link where I found the description:
Arduino RTC Turorial - Sparky's Widgets
I have been using happily this library in my projects.

Now, I would like to migrate to an Arduino Due, which strictly requires the Arduino 1.5 IDE.
I have dowloaded the ARDUINO 1.5.4.

My problem:
there is now something wrong with the library when using it with ARDUINO 1.5.4 (see errors pasted below when testing compilation without upload; I am still using a Mega for this test, and no DS3231 is hooked to the mega) ).

The attachment file contains the small test program, and the .h and .cpp library files
Could someone help for this ?

Thanks

Under ARDUINO 1.5.4, I get the following compiling errors:

You need to port (re-write) the code for the Due as it is not an AVR chip. Most likely you have problems with any direct port manipulation and with SPI.

OK, sorry. :~
It was a silly mistake: I had included the "DS3231RTC" library, but it needed also a "TIME" library in addition.
It now works on Arduino 1.5.4.

In my last message,
things went fine for compilation under Arduino 1.5.4, and selecting the arduino Mega 2560 board.

STILL A PROBLEM:
When now selecting an Arduino Due board under Arduino 1.5.4, and trying to compile,
I get error messages (see below).
I have no clue of what is causing a problem, and the error message is cryptic: the only '' in the .h file are in a block comment, and at line 31, there is no ''

Help!
