Re: [PATCH] ws2_32: Check WSAStartup before using WSAHton(l|s)

[Zebediah Figura (she/her)]

Hello Walter, thanks for the patch!

Note that all patches need a Signed-off-by tag, to denote that the patch 
meets the technical and legal requirements of the project.

With respect to the content of this patch, do you have an application 
that needs this? Failing that, I'm not sure it's worth adding to the 
code. Yes, the tests confirm it, but it's more code to add for no good 
reason.
