+Subject: [PATCH] Check if wordexp function is supported
+
+eglibc could be configured to build without wordexp, so it is not enough
+to check if wordexp.h exists (the header file could be installed, but it's
+possible that the wordexp() function is not supported).  An additional
+check if wordexp() is supported by the system C library is needed.
+
+Upstream-Status: Pending
