comexk at gmail dot com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |comexk at gmail dot com --- Comment #16 from comexk at gmail dot com --- IMHO it would be very useful to have an extension to force the compiler to accept these casts, and anything else that GCC is capable of constant-evaluating but the standard overly-conservatively rejects.
