latest strace downloaded from sourceforge ,
strace -V -> 4.4.90 , dir says 4.4.92 .
tracing wine install issues msg in summary.
(manuall copied in).
/usr/include/asm/unistd.h
#define __NR_vfork 190
wine install does use vfork
but the switch in util.c doesnt have one for vfork.
(bears no resemblance to 4.4.2 version).
4.4.2 was/is ok.
