Last comment as I've made it to the end of the patch.

Your testcases are all free source form.  In fixed 
form, gfortran would need to deal with 'u = 1 2 3 4 u _8'
I don't have the patch in my tree at the moment,
it isn't clear to me if the matcher for an unsigned
constant is prepared to deal with space between 4 an u
in the above.  The match_digits likely leaves the 
current locus at u, but I'll need to go check that.
