RE: [GD-Windows] Compiler code gen

[Jon W. <hp...@mi...>]

This is the well-defined behavior both of how arguments get
passed through ellipsis, and how the va_arg() macro works. It's
just one of those things, like "don't read memory after you've
free()-ed it" or "don't use single-equals in conditional
expressions." It bites you once, and you learn to deal with it.
The type promotion through ellipsis is how ALL arguments got
passed to functions back in K&R C -- just be grateful you have
the tighter ANSI type scoping for non-ellipsis arguments ;-)

Cheers,

Doh! Not very many holes, but one new one.  My gripe with CodeWarrior is
that it recognizes the float being passed and promotes it to double from the
caller, then I try to retrieve it with the type float and obviously it knows
that it must promote that to double but doesn't.  I'm not sure it's a
standard problem as much as their implementation of the va_arg function.
