[Rd] 3.5 on Tiger

[Jan de Leeuw]

setenv CC gcc-3.5
setenv F77 gfortran
setenv CXX g++-3.5

What I had to do.

1. Build a local zlib-1.2.1
2. Compile ppr.f in stats with g77-3.4 and not with gfortran-3.5
3. Change line 1581 in plot.c to

                double *aa = REAL(cex);
                 if (R_FINITE(aa[i % ncex])

      i.e. get the assignment out of the macro

4. Disable the DO_STR_DIM macro in plot.c (and thus the
functions do_strheight and do_strwidth). This could be fixed by
expanding the macros and pasting into the source.
