-Subject: [PATCH] Add support for defining missing funcitonality
-
-In order to support alternative libc on linux ( musl, bioninc ) etc we
-need to check for glibc-only features and provide alternatives, in this
-list strndupa is first one, when configure detects that its not included
-in system C library then the altrnative implementation from missing.h is
-used
