It's much worse than you can imagine!
`strings /proc/kcore | grep GNU' >qqq.qqq`
Causes a file this big to be generated: -rw-r--r-- 1 root root 1069748 Oct 9 10:01 qqq.qqq
That's how much space is being wasted by GNU advertising.
A single program:
int foo;
Compiled, produces this:
.file "xxx.c" .version "01.01" gcc2_compiled.: .comm foo,4,4 .ident "GCC: (GNU) egcs-2.91.66 19990314 (egcs-1.1.2 release)"
It __might__ be possible to link, without linking in ".ident", which currently shares space with .rodata. My gcc man pages are not any better than the usual Red Hat so I can't find out if there is any way to turn OFF these spurious strings.

I was going to compile a list of innovations that could be attributed to Microsoft. Once I realized that Ctrl-Alt-Del was handled in the BIOS, I found that there aren't any.
