Questions on proprietary program using gcc libraries

[jim.brown]

I've searched this forum and did not find any guidance.

I am building a proprietary shared library with gcc. The normal
C++ runtime routines (memcpy etc.) are dynamically linked.

1. Can I sell my application since it uses the C runtime.

2. If I sell it, am I correct that it falls under the LGPL license.

3. If the person who buys does not have gcc, can I distribute the
   C++ runtime libraries libgcc_s.so.1 libstdc++.so.5 with my product.
   If so, how do I reference their license?

I am on Solaris 9 and RehHat Linux 9.

Thanks for the help. I have been unable to interpret the LGPL by myself.
