Paul Smith 15dfad96d7 [SV 63439, SV 63452] Don't warn on undefined internal variables ... Don't generate undefined variable warnings for variables that are internal / special to make and where the empty string is valid. Rather than defining them to empty, which could introduce unwanted behavior, keep a list of variable names which we should never warn about. * src/variable.h (warn_undefined): Convert the macro to a function. * src/variable.c (defined_vars): Always "defined" variable names. (warn_undefined): Implement as a function and check against the defined_vars before generating a warning. * src/read.c (read_all_makefiles): No need to reset warning flag. * src/vpath.c (build_vpath_lists): Ditto. * tests/scripts/options/warn-undefined-variables: Expand all the pre-defined variables to ensure warnings are not generated.		2022-12-24 10:52:49 -05:00
