Hmm. I suppose there'd be no license issues with borrowing a BSD qsort.
But I can't see any reasonable way for configure to decide automatically
whether we should replace the system qsort. I think we'd have to put
a USE_PRIVATE_QSORT symbol definition into src/template/solaris.
Can anyone see a problem with doing it that way --- are there any
versions of Solaris where this'd be a bad idea?
