gcc 3.4 Regex problem

gcc 3.4 Regex problem
Hello All,
I have been using String.h with gcc 2.95. Now I have upgraded to gcc 3.4. The support for String.h has been removed and I believe Regex.h support is also not inbuilt. So I tried to build my own library for String.h. I had to use Regex.h and rx.h for a succesful library compilation. The name of library is libstring.a and is located in /usr/local/lib.
On linking it in the code and doing a make I get the unreferenced usage for few functions from rx.cc. I dont know why, Please help in this:
