Hm, what version of env is that?
I only checked on a couple of systems that env -S exists, but it might
not be available (e.g. now I'm looking, at least busybox env does not
provide -S)
OTOH, we need -S to split arguments because the kernel splits the
shebang as [binary, single argument], so without it awk wouldn't work.
Apparently gawk can work without an explicit -f is invoked as gawk (so
could be used without -S), but that won't be much better wrt
compatibility in my opinion.
I don't see any way to make this work out of the box for me (awk not in
/usr/bin) and you (env not supporting -S), but I guess I can keep that
patch around locally...
Sorry for the trouble.
