Simon, can you explain me using simple words what the problem was and
how you did solve it (without details... ). In fact I have both GNAT GPL 2014,
and GNAT GPL 2012 / SPARK 2012 on my iMac, and I want to avoid loosing
the 2012 version that I use for Spark... So do you think that there will be a
problem with Spark or not ?

Kind regards,

Vincent
