[Help-gsl] Ranges for random generators

[Sergey Ivanov]

Looking for generator with 64-bit range. for gsl_rng_alloc function.
This is a list oif all possible generators (if env GSL_RNG_TYPE is
wrong then this list return gsl_rng_env_setup):
Valid generator types are:
           borosh13               cmrg            coveyou          fishman18
          fishman20          fishman2x              gfsr4           knuthran
          knuthran2       knuthran2002          lecuyer21             minstd
                mrg            mt19937       mt19937_1999       mt19937_1998
               r250               ran0               ran1               ran2
               ran3               rand             rand48      random128-bsd
   random128-glibc2    random128-libc5      random256-bsd   random256-glibc2
    random256-libc5       random32-bsd    random32-glibc2     random32-libc5
       random64-bsd    random64-glibc2     random64-libc5        random8-bsd
     random8-glibc2      random8-libc5         random-bsd      random-glibc2
       random-libc5              randu               ranf             ranlux
          ranlux389            ranlxd1            ranlxd2            ranlxs0
            ranlxs1            ranlxs2             ranmar             slatec
               taus              taus2            taus113         transputer
              tt800                uni              uni32                vax
         waterman14                zuf

So, i tried mt19937_1998, random64-bsd, random64-glibc2,
random256-libc5 and in first case

gsl_rng_max returns 4294967295, in other cases - 2147483647...

Box is 64-bit, sizeof(int)=4, sizeof(long int)=sizeof(long long int)=8
