--- Comment #8 from Martin Sebor <msebor at gcc dot gnu.org> ---
C makes it a constraint that in the #line directive:
The digit sequence shall not specify zero, nor a number greater than
2147483647.
Both GCC and G++ issue a pedantic warning for the directive so I think they
both do the right thing and already implement the requested behavior. There
could be a warning option to control this warning separately from others but
that seems like a separate issue that applies to a number of other warnings as
well.
gcc -O2 -S -Wall -Wextra -Wpedantic -xc++ /build/tmp/a.c
pr90476.c:1:7: warning: line number out of range
1 | #line 0
| ^
pr90476.c: error: ‘mytypo’ does not name a type
With that I think this can be resolved.
