 SwissTorExit reports a compile error on Kubuntu 11.10 amd64, with GCC
 4.6.1:
 {{{
 compat.c:1667:15: erreur: redundant redeclaration of âenvironâ [-Werror
 =redundant-decls]
 /usr/include/unistd.h:542:15: note: previous declaration of âenvironâ was
 here
 cc1: all warnings being treated as errors
 }}}

 Apparently `extern char **environ;` isn't always harmless.
