Nine new RNGs ported to GSL

Nine new RNGs ported to GSL

[Carlo Perassi]

Hi, everybody.
In the last two months, with the help of Brian Gough, I ported to the GSL nine
new random number generators. I will try to port three other RNGs but I don't
have a deadline for this second task.

The nine new RNGs pass `make check` on a 32 bit system.
Brian told me sometimes a RNG who pass `make check` on a 32 bit system fails on
a 64 bit system so I am looking for some volunteers with 64 bit systems who
want to try them on their machines.

The patch is available here:
http://www.linux.it/~carlo/somehacks/gslrngptc/

How to patch and test:
- download the latest version of GSL (1.0 at the moment)
- download the latest version of gslrngptc (1.0 at the moment)
- tar zxvf gsl-1.0.tar.gz
- cd gsl-1.0/rng
- mv ../../gslrngptc1_0 .
- patch -p1 < gslrngptc1_0
- cd ..
- ./configure
- make
- make check | tee ckres

You will get a ckres file with the results of the tests over the various
libraries: if you don't get any errors it works well.

Thank you very much for your time.

I tried make check with new RNGs on Tru64 Unix 4.0f Alpha (ev67). While
stock gsl-1.0 works fine with both cc and gcc, with patch I get
making check in rng

Unresolved:
gsl_rng_borosh13
gsl_rng_fishman18
gsl_rng_fishman2x
gsl_rng_knuthran2
gsl_rng_knuthran
gsl_rng_lecuyer21
gsl_rng_waterman14
gsl_rng_coveyou
gsl_rng_fishman20
collect2: ld returned 1 exit status
for both

must be some makefile/include issue?
probably nothing to do with 64-bitness.

I repeated twice the whole procedure but I didn't get any error.
May I know the complete sequence of your operations?
May I see the output of `make check`, if you got one?

Thank you very much.

It worked ok for me on,

$ uname -a
Linux usf-cf-alpha-linux-1 2.2.18pre21 #1 Wed Nov 22 05:08:09 CST 2000 alpha unknown

I got a few warnings about 'unused variables' with -Wall, but that was
all.  I didn't get any errors for unresolved symbols -- not sure what
is going on there.
