That particular machine self-destructed, so I don't have an adequate 
record of what versions of gld/ld were installed. A rebuilt system using 
the SunFreeware libraries etc. (which are for Solaris 10 rather than 11) 
appears to be OK, except that SunFreeware binutils installs ld (not gld) 
in /usr/local/bin which has the result that an older (buggy) version of 
gld is picked up by FPC before the correct one. Creating symlinks 
/usr/local/bin/gld etc. appears to fix the problem.

I'm currently trying to put some minor updates into 
http://wiki.lazarus.freepascal.org/Lazarus_on_Solaris in case anybody 
else is still interested.
