Hello
I am getting this warning,
warning: multi-character character constant

I know why I am getting this error, since I am comparing an integer to a two letter string constant in single quotes,

#define CMD_ID 'ID'
int iCommand;

switch(iCommand)
{
case CMD_ID: // warning: multi-character character constant
break;
}

But I cannot modify the code to prevent as that leads to many changes. Rather I want to suppress the warning. How can I do it in eclipse IDE or inside the code? My program is in C in Linux.

As encouraged by the sticky posts at the top of this forum, please ask
C/C++ development questions in the Eclipse CDT forum.
