--- Comment #2 from Nick Clifton <nickc at redhat dot com> ---
Hi Rainer,

  The warning is intended to alter users to the fact that a segment has been
created with all three permission flags set - something that is very tempting
to attackers looking to inject code into a binary.

  Disabling the warning for specific target configurations is possible however.
 There is a section of code at the start of ld/configure.tgt to do this.  

  I have gone ahead and added the sparc-solaris targets to the list of targets
for which the warning should be supressed by default.  (It can still be enabled
via a command line option, if the user so desires).

Cheers
  Nick
