+Subject: [PATCH] distinguish XSI-compliant strerror_r from GNU-specifi
+ strerror_r
+
+XSI-compliant strerror_r and GNU-specifi strerror_r are different.
+
+ int strerror_r(int errnum, char *buf, size_t buflen);
+ /* XSI-compliant */
+
+ char *strerror_r(int errnum, char *buf, size_t buflen);
+ /* GNU-specific */
+
+We need to distinguish between them. Otherwise, we'll get an int value
+assigned to (char *) variable, resulting in segment fault.
+
+Upstream-Status: Inappropriate [musl specific]
