g++ warning

[Bill Allombert <allomber@math.u-bordeaux.fr>]

Hello PARI developers,

I have fixed a c++ incompatibility in divrr_with_gmp.

There is a warning in src/basemath/arith2.c that is probably linked with
Ilya patch.

~/pari++/Olinux-i686-gmp $ make gp
g++  -c -O3 -DGCC_INLINE -Wall -fomit-frame-pointer    -DBOTH_GNUPLOT_AND_X11 -I. -I../src/headers -o arith2.o ../src/basemath/arith2.c
../src/basemath/arith2.c: In function `ulong good_arena_size(long unsigned int,
long unsigned int, long unsigned int, cache_model_t *, long int)':
../src/basemath/arith2.c:332: warning: assignment to `ulong' from `double'
../src/basemath/arith2.c: In function `unsigned char * initprimes0(long unsigned int, long int *, ulong *)':
../src/basemath/arith2.c:453: warning: `double' used for argument 1 of `good_arena_size(long unsigned int, long unsigned int, long unsigned int, cache_model_t *, long int)'

Cheers,
Bill.
