Anders says
<<when compiled ( gcc -c filename ), generates the following error:
'pragma "Export" requires separate spec and must come before body'.
The example is directly out of the GNAT Documents INTRO Rev 1.98, from
the section 'Building a Program where the Main Program is not in Ada'. I
have now seen various examples with 'pragma Export' used this way, the
implication is that this should work.>>
Nope, the example is wrong (and does not appear in the current GNAT
documentation). The message is exactly right. Pragma Export cannot be
applied to a frozen entity, but a body freezes everything. So you
MUSt have a separate spec, and the pragma EXPORT must come before thhe
body -- typically it is associated with the spec (which makes sense, it
is certainly part of the interface!)
