[sudo-workers] porting sudo to minix 3

[Debjit Biswas]

Hi all,

i've trying to port sudo-1.7.0 to MINIX 3. the problem is MINIX does
not implement supplementary groups.
Although i've been able to compile sudo successfully, running sudo
fails with the message

internal error, tried to emalloc2(0)

This is due to the fact that the getgroups function always returns 0.
Is there any way to detect this during configuration ?
