No, tool/mkctimec.tcl makes the declarations part of the src/ctime.c code. Unfortunately you have to manually "stuff" the output of the script into the middle of the ctime.c code replacing the autogenerated declaration part. This is unlike tool/mksqlite3c.tcl and tool/mksqlite3h.tcl which make the entire sqlite3.c and sqlite3.h files or mkpragmatab.tcl which makes the pragma.h file for you.
