This is on Sage 3.4.1 (my own build).

Got:
;; Loading file /home/dagss/.clisprc ...

<BLANKLINE>
-- Function: gcd (<p_1>, <p_2>, <x_1>, ...)
Returns the greatest common divisor of <p_1> and <p_2>. The flag
`gcd' determines which algorithm is employed. Setting `gcd' to
`ez', `subres', `red', or `spmod' selects the `ezgcd',
subresultant `prs', reduced, or modular algorithm, respectively.
If `gcd' `false' then `gcd (<p_1>, <p_2>, <x>)' always returns 1
for all <x>. Many functions (e.g. `ratsimp', `factor', etc.)
cause gcd's to be taken implicitly. For homogeneous polynomials
it is recommended that `gcd' equal to `subres' be used. To take
the gcd when an algebraic is present, e.g., `gcd (<x>^2 -
2*sqrt(2)*<x> + 2, <x> - sqrt(2))', `algebraic' must be `true' and
`gcd' must not be `ez'.
<BLANKLINE>
The `gcd' flag, default: `spmod', if `false' will also prevent the
greatest common divisor from being taken when expressions are
converted to canonical rational expression (CRE) form. This will
sometimes speed the calculation if gcds are not required.
<BLANKLINE>
<BLANKLINE>
There are also some inexact matches for `gcd'.
Try `?? gcd' to see them.

true
