Program fails to build on MSVC
Forgot to actually make an issue post for this.
For some reason MSVC has a problem with us overloading a binary operator and as such fails to build.
in specific it hates this one and gives the error "binary '+': no operator found which takes a left-hand operand of type 'dvertex_t' (or there is no acceptable conversion)", even though our overloaded operator only accepts dvertex_t in both the left and right slots.
dvertex_t operator+(dvertex_t lhs, dvertex_t rhs)
{
return lhs += rhs;
}
It probably would hate the other operators too but this is the first one it sees so it is the one that errors.
#14 attempted to fix this, but it unfortunately still errors out, although it complains about += instead of +. Oddly, with that error it seems to complain inside our + operator instead of when the + operator is called.
This builds and works correctly on other compilers like Clang, and even VS's intellisense seems to understand it.
