[Gsll-devel] make-marray, :cl-array keyword

[Liam Healy]

OK I "fixed" this problem by removing the :cl-array keyword
to make-marray, which was obsolete.  The :data keyword does
work; the argument should be made by make-ffa, e.g.
(make-marray 'double-float :data (c-array:make-ffa 'double-float
:initial-contents '(1.0d0 2.0d0)))
However this isn't really intended for users; I am working on
a better user interface.
