I have a code snippet that looks roughly like this: extern void my_free(void* ptr); int foo() { volatile long * bar; ... my_free(bar); }This generates the warning 'cast discards qualifiers from pointer target type' at my_free() (gcc 3.4.3). Other than disabling the flag that generates the warning (in general I want these warnings!), how do I suppress this? my_free is of course a free() wrapper, i.e. I don't see any problems discarding the qualifier at this point. I already tried this, which seems like it used to work (I am moving the code from one project to another):my_free((void*)bar); ...and it doesn't help.
Hmm, maybe the problem is -Wcast-qual... does that cover both implicit *and* explicit casts, or just explicit ones? Is there a way (like, I guess, const_cast in C++) to selectively disable a -Wcast-qual warning?
