Auto-port 4.1: Fix implementation of strerror_r_xsi for GNU#16561
Merged
Conversation
Motivation: We did not clear errno before calling strerror_r(...) and then later use it to detect if there was an error. This could lead to false-positives as strerror_r(...) does not set errno to 0 on success. Modifications: Set errno to 0 before calling strerror_r Result: Correct implement strerror_r_xsi for GNU (cherry picked from commit 1fda0d5)
