[PD-dev] seteuid vs. setuid

[Hans-Christoph Steiner]

Hey,

I was just merging 0.41 vanilla into pd-extended 0.40 and noticed  
something worthwhile to point out.  It seems there isn't a patch  
submitted for this, but it is quite simple.  Basically, in s_inter.c,  
'seteuid()' is used to lose setuid privileges.  As far as I understand  
it, seteuid() allows the program to keep the root privilege and switch  
back and forth between root and non-root.

In Pd, it seems it should use setuid() which means change to the new  
UID and lose the old one completely.  Once it starts, it shouldn't  
need to switch back, right?  Pd-extended 0.40.3 has this change in it  
and it seems to work fine.
