So, as it is, the fix doesn't meet those requirements and shouldn't
be applied, right?  If that's the case, then perhaps the first question
is to figure out why someone is running the testsuite as root... Is
that a sysadmin who is building GDB as root?

I had checked that the new functions used are defined by POSIX,
but confess I never worried about Windows. Sorry.
