Probably just a matter of what was needed at the time these functions
were implemented.

In libguile/random.c, look for "SCM_DEFINE (scm_random_normal_vector_x".
Unless you already have a copyright assignment on file for Guile,
though, it's simpler if we add the necessary function and you review
it. I'm not an expert on this code, but it looks as though all we
need is a copy of scm_random_normal_vector_x with scm_c_normal01
replaced by scm_c_uniform01. Does that sound right to you?
Regards,
Neil
