The reason for GETGROUPS_T (which POSIX requires to be gid_t)
is that some systems, like sunos413, fail to conform to posix
by using int's instead of gid_t's for the arrays of groups.
This change is for pedantic consistency, NULL being all zeroes
for all the hardware I ever deal with.
About the core dump...
It looks like the binary built on 413 runs fine on 414 but dumps core
on a 413 machine. The same thing occurs with a statically linked binary.
Also the same with a binary built on 414. So the problem is in
my malloc library, I think. It isn't the realloc(NULL,n) bug.
Suggestions?
