[gobo-eiffel-develop] Expanded types cause error in generated C code

[Wolfgang J. <wj...@so...>]

Hi,

when experimenting with the "gec" it happened
that C compilation failed if the Eiffel code contains
entities of expanded types.
There are two kinds or errors:
- wrong arrangement of type definitions in the *.h file
- bad initializer of local variables
 (0 when a struct is expected)

I tried several modifications of routine
`ET_C_GENERATOR.print_types' to rearrange type definitions
and achieved improvements but no satisfying solution.
Probably, the routine must follow the graph of client
relations (at least the subgraph of attribute relations)
such that the "typedef" declarations are written
in the pre-processing phase (to have the corresponding
_pointer_ types defined in case of a cyclic dependency)
whereas the "struct ..." definitions are written in
the post-processing phase (when all attribute types
have been processed).

PS:
The attachment contains the Eiffel classes of an example,
an ACE file, and the compiler messages (for both, "cc" and "gcc").

PPS:
Maybe you got this message a second time: I sent it a second time
since the mail server told me that the original message had not been 
delivered.
