Trunk merged into fortran-exp branch

With gfc_constructor_append_expr (&tmp_sym->value->value.constructor, ...
I get a lot of failures while regtesting, the few I have investigated
gives "f951: internal compiler error: Segmentation fault" and the backtrace
is:

Program received signal EXC_BAD_ACCESS, Could not access memory.
