These symbols are produced internally by GCC to create global  
constructors which must be run before main().  They should never  
appear as undefined symbols if GCC has been properly installed for  
your software environment (including all languages).  If you are  
having such problems, then C++ code with static objects should also  
fail (is that the case?).

One question here would be which assembler and linker are being used  
in these compiles?  (I understand that Sun offers multiple compiler  
packages.)  It's possible that you've built GCC in a way that assumes  
a smart assembler/linker, whereas the one you have is sufficiently  
feeble to require collect2.  For more information on how GCC deals  
with constructors and linkers, see the section ``How Initialization  
Functions Are Handled'' in the GCC manual.

I've tested W3Kit on Solaris 2.3, with GCC 2.5.8 built for target  
sparc-sun-solaris2.3.  In this installation, the parts of the compile  
process delegated to Sun-supplied tools were as follows:

   as: "SC3.0 early access 01 Sep 1993"
   ld: "Software Generation Utilities (SGU) SunOS/ELF (LK-1.3)"
