I said in a previous msg

<<Or borrow the Spawn from GNAT, I don't think that unit uses much special
GNAT stuff. Borrowing runtime stuff from GNAT to use with other Ada 95
compilers is perfectly possible (in fact last I knew Aonix delivered
Object Ada with some of the intact -- though somewhat out of date --
library units from GNAT).

One thing I should add here is that it is definitely NOT the case that
all GNAT units can be borrowed. I have run across a number of situations
in which people expected for example that they could get the facilities
of the information systems annex just by borrowing the relevant GNAT
packages but that won't work unless:

(a) Your compiler supports high precision decimal types with proper 
Ada 95 semantics (i.e. decimal semantics, not ordinary fixed-point semantics)

(b) Your compiler supports the necssary intrinsic subprograms and other
special GNAT features.
