[Jim Meyering]

FYI,
I noticed unnecessary mktemp simulation in test logs on Solaris 5.11.
This fixes it:

Subject: [PATCH] init.sh: portability fix: use env's POSIX-specified -i option 
not -u

* tests/init.sh (mktempd_): Use env -i and set PATH explicitly rather
than unportable env -u.  Solaris 5.11's env lacks support for -u.
