we just established a new record of postings per month ;-).

Marti, you don't need the -i option. This is only needed by people who 
use the STU mode to produce a library. In this special case, the 
*.cc/cpp files are compiled with -c. The weaver expands the header files 
that belong to the project (-p option(s)) automatically in the generated 
*.cc/cpp files. Therefore, for the translation of the library itself 
nothing else is needed. However, users who want to link their 
applications with the library need transformed header files. In order to 
provide these header files, the library developer has to use the -i 
option, which transforms the header files of the project all at once.

The bug, which you have described, is strange, because the generation of 
the declaration of the exec_old_... function is a quite fundamental 
transformation, which definitely works.

I guess that your header files are located in a different directory than 
the *.cpp files and that you didn't use a -p <src> -d <dest> pair for 
the header file directory. Therefore, ac++ doesn't *know* that these 
files belong to your project and doesn't transform them.

How does your directory structure (and your command line) look like?
