Description SpanKY gentoo-dev 2003-12-25 14:53:02 UTC 
often times i'll see this warning:
In file included from /usr/include/linux/compiler.h:18,
                 from /usr/include/asm/sigcontext.h:4,
                 from /usr/include/bits/sigcontext.h:28,

/usr/include/linux/compiler-gcc2.h:15: warning: `__attribute_used__' redefined
/usr/include/sys/cdefs.h:169: warning: this is the location of the previous definition

usually it's not a problem but sometimes configure scripts choke on it
the fix is simple:
