The ISO never published ammendment 2 for ISO/IEC 10646:2012.

The answer from the Unicode Consortium was (with some copy editing):
Version 7.0 of the Unicode Standard is synchronized with ISO/IEC 10646:2012, 
plus Amendments 1 and 2. Additionally, it includes the accelerated 
publication of U+20BD RUBLE SIGN.

Unicode 8.0, due for publication in the summer of 2015, is in early draft 
stage now, with a page here:
Is intended to synchronize with ISO 10646:2014, plus Amendment 1. 

Therefore Unicode 7.0.0 is between 10646:2012 and 10646:2014.

The wikipedia page is wrong and I have corrected it.

Thus __STDC_ISO_10646__ should be 201304L (the date that ISO/EC 10646:2012
Amd.1 was published).
