I think this is your shell globbing. Do a "set noglob" and then "echo
*linux*", it'll just spit "*linux*" right back at you. And I tried
building a symlink like the one you show... it's useless. Try
executing it with "./cpp" or try doing "file ./cpp" in the directory
with the link, I'll wager they'll report "not found" and "broken
symbolic link", respectively.
What distribution are you using, that sets up /lib/cpp like that?
Or was that done by a gcc "make install"? Hmm...
