DEC really has this down pat in the VAX/Ada compiler.  They have the source
for the Ada interfaces to the Ada RTL available any time you are in ACS.
The source for the libraries themselves are an entirely different manner.
The libraries aren't even written in Ada; the Ada bindings are IMPORT
PRAGMAS to link to the Bliss calling sequences.  The libraries (I would
assume) are written in Bliss-32.  Remember:  "Bliss is ignorance!"  (Terry
Lambert).
