Ah, yes. I totally forgot about that. If you look at the testcase
getenv_1.f90 which I submitted at the same time I submitted env.c, you
see that the name variable is of type

character(len=*), parameter

so it automagically has the correct length. :(

get_environment_variable (the F2003 intrinsic corresponding to getenv)
should suffer the same problem, and ought to be fixed too. I'm
somewhat busy with my master's thesis at the moment and I can't
contribute to gfortran as much as I had hoped, but I'll try to fix
this in a week or so. Unless someone else volunteers, of course. ;-)
