ada: Spurious warning about negative modular literal
If -gnatw.m is enabled, the compiler generates a warning if a unary
minus operator of a modular type is applied to an integer literal.
This warning was being incorrectly generated in some cases where no integer
literal is present in the source code.
gcc/ada/
* sem_res.adb (Resolve_Unary_Op): In deciding whether to emit a
warning about a modular type's unary minus operator being applied
to an integer literal, ignore integer literals for which
Comes_From_Source is False.
