That=E2=80=99s not the *package* name; this is the *variable* name.

We decided to hide =E2=80=9Cgcc=E2=80=9D because over the past few years pe=
ople would
often install it when they wanted GCC =E2=80=94 a reasonable deduction to m=
ake.
But our =E2=80=9Cgcc=E2=80=9D package on its own does not give you a workin=
g GCC =E2=80=93 the
=E2=80=9Cgcc-toolchain=E2=80=9D package does.  So by hiding the =E2=80=9Cgc=
c=E2=80=9D package it is much
less likely that someone looking for GCC will end up with a broken package.=
