>Description:
When compiling C code, this apparently is resolved when using g++ instead of gcc or when compiling C++ code through gcc (as it presumably will call g++), gcc will issue a warning about assignment to a const variable but will allow this to occur any way and create the executable. Even when using the -ansi and -pedantic flags gcc will still create the executable with assignments being made to the const variable. Unless I am missing something about the C standard and other C/C++ compiler vendors apparently agree with me, in that there products do not allow such to occur, I would like to know why gcc allows this C-specific issue to occur.
>How-To-Repeat:
#include <stdio.h>
void main(void)
{
const int i = 0;
i = 1;
printf("i = %i\n", i);
i = 2;
printf("i = %i\n", i);
}

Synopsis: gcc compiles C code with assignments to const variables
State-Changed-From-To: open->closed
State-Changed-By: rodrigc
State-Changed-When: Sun Feb 24 09:29:10 2002
State-Changed-Why:
Using g++, this will not compile.
If you use gcc, then use -pedantic-errors to treat the
warnings as errors which will prevent the code from compiling.
