Documentation now covers the most recent handful of changes

Details matter: the locale_t definition uses an incomplete structure definition, not an anonymous structure.

+- Added support for handling path names which exceed 255 characters in
+  the AmigaOS 2.x/3.x build. This feature works by replacing calls to the
+  CreateDir(), DeleteFile(), Lock(), MakeLink(), Open(), Rename(),
+  SetComment(), SetFileDate(), SetOwner() and SetProtection() functions
+  with a call to a front-end which breaks down long path names into
+  the individual path components. This is a compile-time option which
+  is enabled through the "library/stdio_long_path.h" header file.
+
+  Note that this feature is by default disabled for AmigaOS 4 because
+  its dos.library transparently performs the long path processing
+  by default.

 - The raise() function no longer directly calls abort() because that
   function in turn would have invoked raise(SIGABRT), triggering an

+- The usleep() function now correctly returns 0 and the function
+  prototype reflects this, too. Thanks go to capehill who raised
+  this issue.
+
+- The "struct dirent" which is used by the readdir() function now
+  features a "d_type" member which indicates the kind of directory
+  element the respective entry represents. For the time being,
+  the type can be one of DT_DIR (directory, or hard link to a
+  file), DT_REG (file, or hard link to a file) or DT_LINK (soft
+  link).

+- Implemented the fixes for the tgamma() and tgammaf() functions
+  which were prompted by sodero. Thank you very much!
+
+- The sqrt() function now returns a plain NAN if the function
+  parameter is < 0. Thanks go to sodero for providing the fix.
