Separate run of the TypeCheckMacro converter using the --force flag, for the cases where typedefs weren't found in the same header nor in typedefs.h. Generated initially using: $ ./scripts/codeconverter/converter.py --force -i \ --pattern=TypeCheckMacro $(git grep -l '' -- '*.[ch]') Then each case was manually reviewed, and a comment was added indicating what's unusual about those type checking macros/functions. Despite not following the usual pattern, the changes in this patch were found to be safe. Reviewed-by: Daniel P.
