I found some relevant information on this by:

  1) going to:
http://www.boost.org/doc/libs/1_53_0/libs/fusion/doc/html/index.html
  2) then following the _Class template tuple_ link to:
http://www.boost.org/doc/libs/1_53_0/libs/fusion/doc/html/fusion/tuple/class_template_tuple.html
  3) then following the _vector_ link to:
http://www.boost.org/doc/libs/1_53_0/libs/fusion/doc/html/fusion/container/vector.html

  4) which said:
You may define the preprocessor constant FUSION_MAX_VECTOR_SIZE before
including any Fusion header to change the default. Example:

#define FUSION_MAX_VECTOR_SIZE 20

HTH.
