Using RTLinux with GCC compiler 3.4

Hello,

I am using RTLinux 3.2 with RedHat Linux 7.2.  My RT modules are in C++
and so I use the rtl_cpp.h library. The rtmodules compiled fine with gcc
2.96.  

We have upgraded our gcc to version 3.4, ld version 2.15 and are now
getting the linking errors for multiple symbol definitions, as well as
for symbol size changes (see error list below).  The rtl_cpp file
contains conditional compilation #define statements, which should
prevent these symbols from being redefined.

I was wondering if you could let me know what is wrong in my
configuration/compilation.  
Your help is greatly appreciated; thank you!

Olya Flores.
