hi,

if a C program have:

#include \<ruby.h\>

and autoconf’ed, which meaning it will generate another “config.h”,  
the compiler will report warning like:

/usr/lib/ruby/1.8/i486-linux/config.h:1:1: warning: “PACKAGE\_NAME”  
redefined

The reason being ruby.h include its config.h, and there is a empty  
PACKAGE\_NAME etc. defined there already.

Is there any way I can get rid of this warning?

thanks

oliver
