New to ada95: porting

[Al Johnston <sofeise@mindspring.com>]

I am starting to look at what it will take to port our ada8X code to an
ada95
compiler.  The code does a lot of interfacing between ada and c.
Regrettably
it does this in various way... most all of them are compiler
implementation
dependent.

I am trying to figure out the best way of interfacing various data types
and
have really gotten bogged down.  Is there a faq or howto on this topic
somewhere?

things of particular interests are
1) access types to 1-d unconstrained arrays
2) access types to 1-d unconstrained array whose elements are also
1-d unconstrained arrays.
3) using 'address on an ada string type when interfacing to a c
* char type
4) generation of ada strings by c-code (via calls to ada library
linked into a c program)


thanks
