X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=df7718b5cf61de2e4c1f0452957cc41e0034c576;p=thirdparty%2Fcurl.git

curl: limit Windows-specific code to Windows builds, other tidy-ups

Prior to this patch, some Windows logic, including a Windows-specific
warning message was compiled in for all platforms.

Also:
- fix double space in warning message on UWP.
- formatting.
