Nope, it doesn't. So when libnautilus-private/nautilus-program-choosing.c does:


extern char **environ;
[...]
envp = environ;

the linker crashes because _environ is not a defined symbol. The standard compatibility patch is:

+#include <crt_externs.h>
+#define environ (*_NSGetEnviron())
 extern char **environ;

so the formal solution is to have configure check for that header and symbol, and then do those #include and #define iff the AC_ checks find them (based on HAVE_ tokens).
