http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6843 Removal of MSVC copiler warnings Summary: Removal of MSVC copiler warnings Product: XalanC Version: 1.4.x Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Enhancement Priority: Other Component: XalanC AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Many of the compiler warnings generates by MSVC are due to unreferenced variables (warning C4100). These warnings can be rmoved using the following macro #define XALAN_UNUSED_ARG(a) do{} while(&a==0) and where the warning is issues, the variable responsible for the warning should be passed to this macro e.g void foo(AType* anUnreferencedPtr) { XALAN_UNUSED_ARG(anUnreferencedPtr); } Most compiler optimize this code away (VC++ does) and this macro has the advantage of only disabling the warning when it is consciently removed by the coder (as opposed to using pragmas like #pragma warning (disable:4100) which remove all warning for the current unit. By using this prama, one runs the risk of having an unreferenced variable going unoticed).
