>From where I stand, as long as the Autoconf manual keeps warning about
this, we should not use it.  When the Autoconf folks decide to remove
it, we could revisit this issue and decide whether we can also use it,
depending on what system still have problems with it at that time.

Btw, the Autoconf manual here matters because the Gnu Coding Standards
document points to it as the "canonical" source of portability issues
that GNU projects should consider.
