/************************************************/
Compile the above file with the following options
 g++ -G fun2.cpp -o fun2.so
   ok. compiles and gives the shared object file
 g++ -shared fun2.cpp -o fun2.so
   not ok. kaput!
 g++ -symbolic fun2.cpp -o fun2.so
   not ok. kaput!! once again

State-Changed-From-To: open->closed

State-Changed-When: Fri Apr 26 03:45:20 2002
State-Changed-Why:
    works for 3.0, but you (a) need to add -lc to the -symbolic
    version, and (b) you should read http://gcc.gnu.org/faq.html#dso
    before you do
