Paul,

> (iii) I don't know what is happening below.

I am not sure to really understand the problem, but I find _htab_hash_pointer
in /opt/gcc/gcc4.4w/lib/libiberty.a:

[ibook-dhum] f90/bug% nm /opt/gcc/gcc4.4w/lib/libiberty.a | grep _htab_hash_pointer
000056f8 D _htab_hash_pointer

and collect2 uses -liberty.
