How well are you packing your structs? Arpad asked that question with an awesome Dehydra script and came up with an interesting list.

GCC 4.3.3 Is supported GCC 4.3.3(4.3.[210] worked) broke C++ compatibility in the headers used by Dehydra. Zach pointed out that passing -fpermissive to g++ solves the problem. Sorry to all the people who had issues building the hydras with GCC 4.3.3, that’s fixed now.

As I mentioned before, we are skipping GCC 4.4 support in Dehydra and aiming for supporting unpatched GCC 4.5. I wish that the small GCC patches were as quick to land as that big one I landed a couple of weeks ago :(.
