Comment (by Phyx-):

 Sorry for the delay, haven't had much time to spend on GHC. As you know we
 depend on GCC which gets it's crt definitions from the mingw-w64 project.
 As far as I am aware of, they were supposed to support XP until v5 of the
 crt release https://sourceforge.net/p/mingw-w64/mailman/message/35465862/

 but this function was added in 2010:

             * lib32/msvcrt.def: Added secure and locale type symbols from
 Win7.
             * lib64/msvcrt.def: Likewise.



     git-svn-id: svn+ssh://svn.code.sf.net/p/mingw-w64/code/trunk@3079

 }}}

 Which is why it's using it. But while that means I could in theory have a
 workaround for XP for this, it won't do you much good. Starting with 8.6
 we're going to use system APIs only available in Windows Vista SP1 and
 higher (which is our minimum supported version, but we'll likely be moving
 this to Windows 7 too).

 As @refold said we don't support XP anymore, and I don't think it's
 feasible for us to, it requires too many workarounds in the runtime, and
 in some cases just not having a feature.

 So while I could solve this particular issue, I'm sure it still won't be
 useable.

 Sorry.
