Fix getpwnam_r-handling: getpwnam_r returns (always?) 0, you have
to check result* (pppw[0])!
Truss-log from querying first "root", then "" on SunOS 5.9:
<- libc:__posix_getpwnam_r() = 0
"root"
-> libc:__posix_getpwnam_r(0xff1bf8a8, 0xff1bf460, 0xff1bf490, 0x400)
<- libc:__posix_getpwnam_r() = 0
Yes, that's 0 in both cases. (I wasn't even able to elicit an ERANGE btw.)
