Yes, the cc link on Linux is special to Linux; a `generic' gcc or egcs
installation does not create any cc link.

On my system (also a heavily hacked Debian GNU/Linux 1.3.1) I built
gcc-2.7.2.3 myself as a Debian package and installed it in /tools/gnu
setting up links in /usr; here I saw that the cc link is created by
the debian/rules makefile.
