I may need to revise that. I just noticed the definition of 
"configuration pragma":
"Certain pragmas are defined to be /configuration pragmas/; they shall 
appear before the first compilation_unit of a compilation. [They are 
generally used to select a partition-wide or system-wide option.] The 
pragma applies to all compilation_units appearing in the compilation, 
unless there are none, in which case it applies to all future 
compilation_units compiled into the same environment." (ARM95 10.1.5(8))

I can't find a definition of "compilation", other than that it consists 
of any number of compilation units, but I guess that, in the case of 
Gnat, each invocation of Gnatmake is a single compilation. If so, then 
pragma Character_Encoding must not be a configuration pragma, because it 
would apply to any library units that Gnatmake decides to recompile, and 
those may be written by someone else in some other encoding.

We could let pragma Character_Encoding apply to a single file, a single 
compilation unit, an entire hierarchy of child packages or whatever, but 
we can't have it apply to everything that happens to be compiled at the 
same time. It must be tied to a specific piece of code.
