Thanks for checking!

Now we have two choices (w.r.t the message I quoted above):
Enable -mimpure-text on sparc-solaris/gcc which would allow non-PIC code
in dso's.  Or disallow non-PIC in dso's (and adjust demo-nopic.test).
Or create a dedicated flag (let's call it `impure_flag') for non-PIC
code in dso's.

I vote for the second option, since portable code should not depend on
it (in the name of a sensible common subset of features).  What do the
others think?

Second, I think Ralf Menzel is right that Solaris wants
-      _LT_AC_TAGVAR(no_undefined_flag, $1)=' -z text'
+      _LT_AC_TAGVAR(no_undefined_flag, $1)=' -z defs'

Do the others agree?
