contents of the statement program header, including the
include directory and file name tables.
(read_file_scope): If we have line number info, instead of just
calling dwarf_decode_lines to do all the work, call

2) In read_tag_string_type(), a fix for FORTRAN that propagates the
first string length to all string types. This is important as FORTRAN
strings are not delimited as in C/C++.

variable by reference to read_partial_die.
code in loop condition. This seemed to be trying to round
info_ptr up to the next four-byte boundary, but that's not what it

trying to address, we can fix it properly.
