The whole delayload/__try/__except stuff may be unneeded in 2.4, because
it will most probably be compiled with MSVC7.1, installed via an msi
installer, and all systems where the msi actually could be installed
would already have a winsock (or winsock2) dll.  At least that is my
impression on what I hear about systems older than (or including?)
win98SE these days.
