Is there anybody who already tired to generate a library for the 
EFSL by Sourceforge  using the Imagecraft ICCARM Compiler ?

Most of the  modules can be compiled without problems. However, 
I'm getting some strange warnings in some of them during object file
generation, like   

        - unreachable code
        - arguments with no use

        - local variable is used but the references are unreachable
        - calling function without prototype

I assume there are problems due to different syntax between ICCARM 
and the GNU Compiler. Are there similar warnings while compilation
with the GNU compiler ? (I do not know the GNU)

I understand the reason for the first two warnings , but I'm almost a
bit frustrated because I'm unable to find the reason for last two.

Any information is appreciated.

Thanks
