to be included into this one. This works the same way as #include does in C; as far as the user is concerned, the included file is inlined into the current one. Since config(8) is no longer limited to working on one user-supplied file, printing just a line number in an error message is not sufficient. The new global variable yyfile represents the file currently being parsed, and must be printed as well. Reviewed by: imp Obtained from: OpenBSD
