Building libssp in C11 mode shows a warning for 64bit configurations, ../../../src/libssp/gets-chk.c:62:12: warning: return makes pointer from integer without a cast [-Wint-conversion]
Currently working around by adding a prototype in gets-chk.c, conditionally defined by the inverted condition found in glibc's stdio.h. Is there a better approach? Matthias
