there is update of libHx from Jan Engelhardt git://git.code.sf.net/p/libhx/libhx http://sourceforge.net/p/libhx/libhx/ci/master/tree/include/libHX/defs.h#l93 It is simpler (does not need __builtin_choose_expr which can be problematic on some old GCC where I have noticed some bug report exists). On the other hand error message would not be so self explanatory. The trick with +0 is clever and newer C standard allows it even for void*. I have tried something similar to overcome comma operator not allowed in initializers. I put my previous attempt there, because there can be place to use that for some non pointers casting (typeof((typeof(new_type[1])){0}[0])) This madness is equivalent to (new_type) but allows to place test [1-2*!!test] onto [1] position to cause build time error.
