I'm interested to know which vendors are serious about supporting the
standard.

What do you mean by "genuine"? AdaCore has been far, far more
proactive with Ada 2005 support than any other vendor. Other Ada
compiler vendors are seemingly moribund, a sad situation.  Rational
Apex used to be a great product, but IBM has let it atrophy, making
absolutely no effort to be competitive or market it to new customers.
From what I've observed, they care nothing about customer retention
for Apex and ClearCase.

Also, there is an old (April, 2008) announcement on
http://www-01.ibm.com/support/docview.wss?uid=swg21221323.  But unless
IBM changes their business model for Apex, its will come too late to
be competitive.
