I don't want to force every programs linked against libpari to also link
a set of graphical libraries that depend on the option used to configure
libpari.

A minima I would like the program below compile and link fine with the
command

gcc main.c -lpari

----main.c----
#include <pari/pari.h>
int main(void)
{
  pari_init(4000000,500000);
}
--------------

and don't require to issue -lX11 or something else.

As of now this is broken:
/home/bill/pari/i686/lib/libpari.so: undefined reference to `plot_outfile_set'
/home/bill/pari/i686/lib/libpari.so: undefined reference to `set_pointsize'
/home/bill/pari/i686/lib/libpari.so: undefined reference to `rectdraw0'
/home/bill/pari/i686/lib/libpari.so: undefined reference to `term_set'
/home/bill/pari/i686/lib/libpari.so: undefined reference to `PARI_get_plot'
collect2: ld returned 1 exit status

Cheers,
Bill.
