      gdb: add accessors to struct dynamic_prop

An existing bug was exposed in the Fortran type printing code.  When
GDB is asked to print the type of a function that takes a dynamic
string argument GDB will try to read the upper bound of the string.

The read of the upper bound is written as:

    if (type->bounds ()->high.kind () == PROP_UNDEFINED)
      // Treat the upper bound as unknown.
    else
      // Treat the upper bound as known and constant.

However, this is not good enough.  When printing a function type the
dynamic argument types will not have been resolved.  As a result the
dynamic property is not PROP_UNDEFINED, but nor is it constant.

By rewriting this code to specifically check for the PROP_CONST case,
and treating all other cases as the upper bound being unknown we avoid
incorrectly treating the dynamic property as being constant.

gdb/ChangeLog:

	* f-typeprint.c (f_type_print_base): Allow for dynamic types not
	being resolved.

gdb/testsuite/ChangeLog:

	* gdb.fortran/ptype-on-functions.exp: Add more tests.
	* gdb.fortran/ptype-on-functions.f90: Likewise.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
