Paul Smith 03ecd94488 Add new warnings invalid-var and invalid-ref ... The "invalid-var" warning triggers if the makefile attempts to assign a value to an invalid variable name (a name containing whitespace). The "invalid-ref" warning triggers if the makefile attempts to reference an invalid variable name. Both new warnings have a default action of "warn". * NEWS: Add these new warnings. * doc/make.1: Document them in the man page. * doc/make.texi (Warnings): Document them in the user's manual. * src/warning.h: Add enum values for the new warning types. * src/main.c (initialize_warnings): Initialize the new warnings. * src/variable.h (undefine_variable_in_set, undefine_variable_global): Ask callers to provide a struct floc specifying where the variable is undefined. * src/read.c (do_undefine): Pass floc when undefining. * src/variable.c (check_valid_name): If invalid-var is enabled, check the variable name. (define_variable_in_set): Call it. (undefine_variable_in_set): Ditto. (check_variable_reference): If invalid-ref is enabled, check the variable reference. (lookup_variable): Call it. (lookup_variable_in_set): Ditto. * tests/scripts/options/warn: Add tests for the new warning types.		2023-04-01 11:13:12 -04:00
