包含iostream时出现xlocnum.h错误

Question

I have some code, and when I don't include iostream everything works, but when I do, I get a bunch of strange errors:

I have never seen this before and don't know what this means...

edit: The ambiguous symbol is unrelated btw, that's already fixed

Answer 1

oke pretty dumb: defined a macro named size, which apparently causes conflicts all of the place:p

I wonder though, wouldn't it be pretty easy for a compiler to figure our whether string->size() should be interpreted as a method call or as string->4, which makes no sense...
