warp at iki dot fi changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |warp at iki dot fi --- Comment #30 from warp at iki dot fi --- Note that a few of the examples in that first tweet are actually misleading. More particularly, the example in png.c. At first glance it looks like C and an example of this mistake, but if you look at the context it becomes clear that it actually isn't C at all (because that line appears in a context where it would be illegal code, namely, inside the initialization list of an array). It's actually BC code embedded in the C source code, for some reason. In BC 2^32 is legitimately 2 to the power of 32. The other examples are probably legitimate, though.
