It has never been and never will be supported. It works most of the  
time (I also usually do it that way), but not always.

It happens if you get circular dependencies with fixes in the RTL: if  
a certain fix requires both changes in the RTL and in the compiler,  
and if the changed RTL can only be compiled by the fixed compiler,  
then we add a conditional define to the RTL which the previous stable  
release to still compile it (possibly with reduced functionality, but  
enough to bootstrap the 2.1.1 compiler).

We don't do this for the 2.1.1 compiler to avoid ifdef explosions.
