Pseteuid/Psetegid errors in 1.11h2

[itschere@techfak.uni-bielefeld.de]

 Ok, I don't use 1.11h2, but I've been reported that it causes problems
with ftpd. Reason seems to be that the newer Psetreuid routines just
return 0 in case of no error. Ok, how are they supposed to distinguish
which id to return, but the 'old' Pseteuid always did this. Since ftpd
relies on this, there's a small fix appended, relative to 1.11h2.

bye,
TeSche
