How to write compile time for user

I would like to write a Pragma warning in GNU g ++ for every user who compiles my codes.

How can i do this? I am using the GNU g ++ compiler.

Support for MSVC and the new GCC:

#pragma message ( "your warning text here" ) 

GCC also uses a different syntax:

 #warning "you warning text here"
