It depends on how your program reads the .c parser file: In one style, the
lexer is inserted into the parser file.

The style you have chosen suggests that you instead want the names in a
special header file. You should make sure that your compiler sees that
header file, either by some compiler command, or by making sure other
C-source files #includes it.
