Purpose
Generates a shared object enabled for runtime linking.
Syntax
Usage
The compiler automatically exports all global symbols from the shared object unless you specify
which symbols to export by using with the -bE:, -bexport:, or
-bnoexpall option. You can also prevent weak symbols from being exported by using
the -qnoweakexp option. 
Symbols that have the hidden or internal visibility attribute are not
exported.
To save the export list to a file, use the -qexpfile option.
Predefined macros
None.
