I want to un-show a specific warning, namely the one about string length: "Warnung: Zeichenkettenlänge »5388« ist größer als die Länge »509«, die von ISO-C89-Compilern unterstützt werden muss" (which translates roughly to "Warning: String length »5388« is larger than the length »509« which is required to be supported by ISO-C89 compilers"). The documentation on http://gcc.gnu.org/onlinedocs/gcc-3.3.5/gcc/Warning-Options.html#Warning-Options does show how to do this.
Please note that I'm quite happy with all other warnings. -- Summary: Documentation: Help on no-show of warning is missing Product: gcc Version: 3.3.5 Status: UNCONFIRMED Severity: minor Priority: P2 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: mail at thorstenhau dot de CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19588
