gp2c , pari library and st99

[Olivier Ramare <ramare@math.univ-lille1.fr>]

Dear all,

  I need the compilation option -st99 to be able
to use the linear programming solver lpsolve
(otherwise, it does not know long long, or so it says :-().
  My understanding of C code is limited, but
the code produced by gp2c does not meet this requirement,
or maybe it is the whole pari library that does not --
  Or maybe I could change the standard in between?

  Any help appreciated!!
  Best,
  Amities,
                    Olivier
