Building on Mac with Clang I get warnings like this:
../../../gcc/gcc/cgraph.h:2629:28: warning: struct 'cgraph_edge' was previously
declared as a class; this is valid, but may result in linker errors under the
Microsoft C++ ABI [-Wmismatched-tags]
It seems to be talking about a MS bug (since C++ says struct and class mean the
same thing other than the default access). Still, I wonder if it would be
worth changing the code to use just one of "struct" or "class" for any given
type. (And then the convention would presumably be that a POD type is called
"struct" and other types are "class".)
