It's not really a problem to set two different ones, but if you like
check out R.W. Hamming "Numerical Methods for Scientists and
Engineers", -- you can generate a gaussian random number by summing 12
uniform random numbers and subtract 6.0. There's a subtle caveat which
explains that this isn't perfect, but in most cases is actually closer
to what you want than a perfectly gaussian random number (i.e. do you
ever really want random number which has probability of 137*sigma, even
if strictly speaking it's bound to happen sooner or later in a true
gaussian distribution?)

Subject: [Help-gsl] random number distributions
Hello,
I wish to use _in same program_ a random number generator which
provides uniformly distributed random numbers _and_ a function which
returns a Gaussian random variate.
Theses functions requires two calls to a random number generator.
So, I'm wondering whether I have to set one or two random number
generator ?
Thanks in advance,
Regards,
Eric.
