On this particular point my threshold of 'portable' is actually pretty
low, as long as it's fail-soft. Failure to detect bad TZ on some
systems would leave them no worse off than before, right?
But I haven't seen *any* published API that directly tells you whether
tzset liked TZ or not --- AFAICT it's supposed to just silently
substitute GMT. Which would be okay if "GMT" were the only allowed
spelling of GMT, but it ain't ...
