Assign to const pointer in C

[Baldrian]

In an older version of gcc, I could cast away const.
When porting to gcc 4.1.2, the compiler complains.

char * const buffer;
...
   (char*)buffer = malloc(SIZE);

In C++, there is a const_cast<>, but how should this be done in C?

Well, does that make sense to you? You define the variable as a constant, meaning it is immutable (cannot be changed). If you're wanting to modify the data of this constant, instead define it without 'const'. Makes sense to me.

Is the gcc complaint a warning or an error? My recollection is that it is a warning. If so, then you don't have to change anything -- just live with it.
