Thomas E. Dickey 027d0c57c4 ncurses 5.9 - patch 20150516
+ amend change to ".pc" files to only use the extra loader flags which
  may have rpath options (report by Sven Joachim, cf: 20150502).
+ change versioning for dpkg's in test-packages for Ada95 and
  ncurses-examples for consistency with Debian, to work with package
  updates.
+ regenerate html manpages.
+ clarify handling of carriage return in waddch manual page; it was
  discussed only in the portability section (prompted by comment on
  Stack Overflow forum):

<H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
The function <STRONG>field_info</STRONG> returns the sizes and other
attributes passed in to the field at its creation time.
The attributes are: height, width, row of upper-left cor-
ner, column of upper-left corner, number off-screen rows,
and number of working buffers.
The function <STRONG>dynamic_field_info</STRONG> returns the actual size of
the field, and its maximum possible size. If the field
has no size limit, the location addressed by the third
argument will be set to 0. A field can be made dynamic by
turning off the <STRONG>O_STATIC</STRONG> option with <STRONG>field_opts_off</STRONG>.
</PRE>
<H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
These routines return one of the following:
<STRONG>E_OK</STRONG> The routine succeeded.
<STRONG>E_SYSTEM_ERROR</STRONG>
System error occurred (see <STRONG>errno</STRONG>).
<STRONG>E_BAD_ARGUMENT</STRONG>
Routine detected an incorrect or out-of-range argu-
ment.

These routines emulate the System V forms library. They
were not supported on Version 7 or BSD versions.
A null (zero pointer) is accepted for any of the return
values, to ignore that value. Not all implementations
allow this, e.g., Solaris 2.7 does not.
