Yeah, too many ifdefs :-(. But I suppose that the initial
"#ifdef LOCALE_ENVIRON_REQUIRED" block is not compiled on sane
platforms, meaning that the first code in the routine is the
unconditional
if (! setlocale(LC_ALL, ""))
setlocale_failure = TRUE;

Indeed; I think a pretty strong case can be made that this is a Perl
bug. It's reasonable to be doing the setlocale call in a standalone
Perl executable, but libperl should just work with whatever locale
settings have been chosen by the surrounding program (ie, all these
calls should be setlocale(LC_xxx, NULL) in the libperl case).

We could just file a Perl bug report and wait for them to fix it.
