Je to novou verzi libc - errno uz neni promenna ale lze se
k ni dostat prez nejakou funkci - zajistuje to aby kazdy thread
mel svoje vlastni errno. #include <errno.h> na vhodnych mistech
by to melo resit. Popr. posledni balicek se zdrojaky qmailu
a uscpi v Debianu unstable by tu opravu uz mel obsahovat
(resilo se to tam cca pred pul rokem).
