+Include cdefs.h wherever it is needed
+
+cdefs.h is included from within a lot of glibc headers, so it almost
+invariably and automagically gets pulled in with glibc.
+
+However, this might not be the case with other C libraries. musl does
+not provide cdefs.h so it does not include it from its own headers
+(cdefs.h must be provided separately).
+
+So we must include it when we are going to use macros it provides.
