We have and provide Curl_strerror() internally for a reason: strerror() is not necessarily thread-safe so we should always try to avoid it. Extended checksrc to warn for this, but feature the check disabled by default and only enable it in lib/

- Change Curl_strerror to use sys_errlist[errnum] instead of strerror to retrieve the error message on Windows. Windows' strerror writes to a static buffer and is not thread-safe. Follow-up to 2f0bb86 which removed most instances of strerror in favor of calling Curl_strerror (which calls strerror_r for other platforms). Ref: curl#7685 Ref: curl@2f0bb86 Closes #xxxx
