Bug 5413 – (diagnostic): No notification that warnings are treated as errors

Not a bug, just a diagnostic suggestion. When compiling with warnings turned on, there is no visual output suggesting whether or not that warning is ignored or enforced as an error: ie: int main() { return 0; return 1; } $ dmd test.d -w test.d(4): Warning: statement is not reachable $ dmd test.d -wi test.d(4): Warning: statement is not reachable Would be handy if confronted with a notification that warnings are being treated as errors by the compiler. This small addition to vwarning has a nice effect: { char *p = loc.toChars(); + if (global.params.warnings == 1) + fprintf(stdmsg, "%s: warnings being treated as errors\n", global.params.argv0); + if (*p) fprintf(stdmsg, "%s: ", p); mem.free(p); $ dmd test.d -w dmd: warnings being treated as errors test.d(4): Warning: statement is not reachable $ dmd test.d -wi test.d(4): Warning: statement is not reachable Regards

Has since been implemented in 2.097.2: spellrecurse.d(6): Warning: statement is not reachable Error: warnings are treated as errors Use -wi if you wish to treat warnings only as informational. Compilation failed.
