There is a function rng_init_rand in glprng.c.  However, the "automatic" 
use of the random number generator is begun in glpmpl4.c, where 
rng_create_rand is used.  This routine appears in glprng.c and calls 
rng_init_rand with a fixed seed of 0.

If you wanted to change this, you would need to modify rng_create_rand 
in glprng.c and probably glpmpl4.c if you wanted to specify the seed in 
the MathProg file.  The worst part might be adding the parsing code for 
whatever new command you add to MathProg to specify a seed.
