Implementing packages for Ada compiler

Implementing packages for Ada compiler

[van-bc!wolfe.wimsey.bc.ca!rsoft!agate!spool.mu.edu!mips!sdd.hp.com!uakari]

	Has anyone out there implemented packages for an Ada compiler?  I  
am facing the task at the moment and would like to hear any warnings,  
horror stories, and bits of advice that folks might offer.  I prefer that
you reply via email.
[Please send responses to compilers as well if of general interest. -John]

I suggest you take a look in either of the following books

1) Methods and Tools for Compiler Construction, Edited by B. Lorho,
   Cambridge University press, 1984.
   This has a chapter by Jean Claude Heliard of Alsys on how their
   separate compilation works.

2) The Rationale for the Design of Ada by Ichbiah & co. (published
   recently in the Ada Companion Series.)  This is more general, but
   does mention some of the work needed in a compiler to support
   separate compilation of packages and so on.

Hope these help,
