That lets them match old-style definitions. It avoids "Type conflict" error messages. It allows shorter function calls.
Fixed the types of some variables in "test/ref/otccex.c". It avoids crashes on 64-bit Windows (32-bit Windows with 64-bit pointers).
The variables named tab and p are used in the context of pointers
and thus must be declared as such. Determining the purpose they
serve, using char over int seems more feasible here as well.
