What is 3.11b2 "based" on ? what is its version history ? does its ancestor
tree ever meet up with the "public" 3.11p version history ? is 3.11b2 GPL ?
which came first the "public" GNAT compiler or the ACT commercial compiler
?

Am I write in presuming that the commerical version came first, since if
the GPL version came first, then commercial version being a modification
would be covered by the GPL and anyone obtaining the 3.11b2 version would
be free to re-distribute it provided they  extended the same GPL rights to
their distribution. Or did ACT develope two Ada95 compilers behind chinese
walls ?
