FORTRAN_HACK macro?

[Michael Elizabeth Chastain]

Beats me.  Here's some fact-crumbs:

  dwarf2read.c was not in gdb 4.16.
  dwarf2read.c was in gdb 4.17, dated 1998-01-28
  1998-01-28 version already has FORTRAN_HACK
  code around FORTRAN_HACK is about the same as it is today
  ChangeLog-96 says dwarf2read.c introduced on 1996-07-19.

grepping on 'read_array_type' in the ChangeLogs turns up:

  1996-12-01:

    (dwarf_read_array_type):  Handle variable length arrays.
    Use lookup_pointer_type instead of handcrafting a type.
    Create array type only if a DW_TAG_subrange_type was found.

  1997-01-25:
    (read_array_type):  Renamed from dwarf_read_array_type.
    Default upper array bound to describe an array with unspecified
    length.
    Create array types in backwards order, as dwarf2 puts out the array
    dimensions from left to right.

  1998-01-28:

    (read_array_type): Fix langauge test.

If the FORTRAN_HACK was in the 1996-07-19 version then I would guess
that it is an unimplemented stub and can be killed/replaced easily.

If it was added after 1996-07-19 then someone was trying to do
something.
