SetThreadErrorMode not found in WindowsXP

[DominicD]

I tried to run my rust binary on WindowsXP however when I use libloading I get an Error which says "SetThreadErrorMode" not found in "Kernel32.dll". In the docs I read the following:

Thread-safety
The implementation strives to be as MT-safe as sanely possible, however due to certain error-handling related resources not always being safe, this library is not MT-safe either.
On Windows Vista and earlier error handling falls back to SetErrorMode, which is not MT-safe. MT-scenarios involving this function may cause a traditional data race;

So I was hoping that SetErrorMode is used which is available on WindowsXP as far as I know.
Is there something I can do to make it work?

If you need more info just tell me
Thanks!

I don't have access to either Windows version so you will need to submit a PR to fix how libloading uses SetThreadErrorMode. It currently checks whether Windows reports the call being unimplemented and then falls back. In retrospective this is linking to the symbol statically, so there needs to be something else (weak linking?) as well.

Thank you for the fast answer.
To be honest I don't have enough knowledge to be able to do something about this myself.
E.g. I don't know what weak linking is.

Following the drop of support for Windows XP by the rust project we will be doing the same.

I'm happy to accept a PR that adds the support back in a non-broken state, however. But given that libstd itself is no longer supporting XP, that will probably end up being quite infeasible!
