dnl Starting around Solaris 11.3, the default 'nm' tool starts reporting
dnl symbols with the 'C' code when given '-p'. Libtool currently cannot deal
dnl with this, and it fails to figure out how to extract symbols from object
dnl files (see libtool bug #22373). To work around this, try to use the GNU nm
dnl instead by default, which is either always or almost always available.
dnl libtool, of course, works with that just fine.

dnl If libtool cannot figure out how to extract symbol names from 'nm', then it
dnl will log a failure and lt_cv_sys_global_symbol_pipe will be unset, but it
dnl will not cause configure to bail out. Later on, when we try to link with
dnl libtool, it will cause a very confusing error message (see libtool bug
dnl #20947).  To try and avoid that bad error message, try to catch that
dnl situation here, closer to when the error actually occurs.
