Paul Smith a0d1e76d60 Add support for .WARNINGS special variable ... Create a new special variable, .WARNINGS, to allow per-makefile control over warnings. The command line settings will override this. Move the handling of warning flags to a new file: src/warning.c. Allow the decode to work with generic strings, and call it from decode_switches(). * Makefile.am: Add new file src/warning.c. * build_w32.bat: Ditto. * builddos.bat: Ditto. * po/POTFILES.in: Ditto. * src/makeint.h: #define for the .WARNINGS variable name. * src/warning.h: Add declarations for methods moved from main.c. Rename the enum warning_state to warning_action. * src/warning.c: New file. Move all warning encode/decode here from main.c. * src/main.c: Move methods into warning.c and call those methods instead. (main): Set .WARNINGS as a special variable. * src/job.c (construct_command_argv): Rename to warning_action. * src/read.c (tilde_expand): Ditto. * src/variable.c (set_special_var): Update warnings when the .WARNINGS special variable is set. * tests/scripts/options/warn: Check invalid warning options. * tests/scripts/variables/WARNINGS: Add tests for the .WARNINGS special variable.		2023-04-02 10:02:18 -04:00
