Hi,

what version of root are you trying to compile?  The existence of
setresuid/setresgid prototypes is checked in the configure script. You
should have 
#define HAS_SETRESUID in your include/config.h

As for the error above it looks like this block of rootd.cxx is compiled 
#if !defined(__hpux) && !defined(linux) && !defined(__FreeBSD__)
static int setresgid(gid_t r, gid_t e, gid_t)
....

which should not happen on linux. You can try to comment the functions
inside the block to test if it is the case.

cheers
Jiri
