lint: model C language levels in a future-compatible way The options -t, -s and -S are confusing because they are used inconsistently. The option -S enables C99 features, but when using it instead of -s, it also doesn't enable all checks required by C90 and later. Prepare fixing of these inconsistencies by replacing the flag variables with language levels that can be extended in a straight-forward way as new C standards arrive. | option | allow_trad | allow_c90 | allow_c99 | allow_c11 | |--------|------------|-----------|-----------|-----------| | -t | x | - | - | - | | (none) | x | x | - | - | | -s | - | x | - | - | | -S | - | x | x | - | | -Ac11 | - | x | x | x | Each usage of the old flag variables will be inspected and migrated individually, to clean up the subtle variations in the conditions and to provide a simpler model. When lint was created in 1995, its focus was migrating traditional C code to C90 code. Lint does not help in migrating from C90 to C99 or from C99 to C11 since there are only few silent changes, and simply because nobody took the time to implement these migration aids. If necessary, such migration modes could be added separately. There is a small functional change: when the option -s is combined with either -S or -Ac11, lint now only keeps the last of these options. Previously, these options could be combined, leading to a mixture of language levels, halfway between C90, C99 and C11. Especially combining traditional C with C11 doesn't make sense, but xlint currently allows it. The 3 tests that accidentally specified multiple language levels have been adjusted to a single language level.
