But if you _did_ have familiarity with Ada (even Ada83) you would know
that Ada has tasking built in to the language.  Thus, based on your
Java comments, C++ is the only one of the three contenders that does
not have built in support for threads/tasking.

To say that a language supports a concept only if the machine involved
has a library to perform that function seems of little value.  Sort of
like saying that a language automatically supports Cobol compilation
given a "Compile_Cobol" library routine.
