I do care about it, but I'm not visualising the case... AFAICS, when built as a host component for a cross to Darwin from non-Darwin, environ would be declared as **environ as usual. If an implementation includes a compiler targetting Darwin that defines __APPLE__ but doesn't provide _NSGetEnviron in its libc, then isn't it broken anyway? Iain
