Compiler warnings in 23.0.92 with gcc 4.3.3

[Ulrich Mueller]

With gcc 4.3.3, I get the following compiler warnings in sysdep.c:

   sysdep.c: In function 'procfs_ttyname':
   sysdep.c:3322: warning: format '%lu' expects type 'long unsigned int', but 
argument 3 has type 'unsigned int'
   sysdep.c: In function 'system_process_attributes':
   sysdep.c:3393: warning: format '%lu' expects type 'long unsigned int', but 
argument 3 has type 'int'

And several others (all over the place) about unused return values of
functions.

        * sysdep.c (procfs_ttyname, system_process_attributes): Fix format
        specifiers in sprintf.
