 It actually is a bug in the documentation. I'm going to add the
 following patch to invoke.texi

 +For C++, a function without return type always produces a diagnostic

 +exceptions are @samp{main} and functions defined in system headers.

 > Why not provide a means to turn off the warnings?
 
 There are already at least three means to turn the warnings off: you
 can fix the header files in your Solaris installation yourself, or you
 can declare the openwin directory as a system include directory, or
 you can change the compiler in any way you want - since you have the
 source code to the compiler.
