Compilation problem with a2ps-4.13

Howdy,

Thanks for a2ps, among all the other great software tools.  I've just compiled it for HP-UX 11.11 using gcc 3.4.5, and need to change it as follows.  This may not be the best fix, but at least is one that works.  I also made a try with HP's compilers, but without success (however I think it's a bug in their C compiler that it doesn't like static inline functions).

diff -C1 -r1.1 lib/quotearg.c
*** lib/quotearg.c	2006/03/22 21:40:44	1.1

  # include <wchar.h>


Below is the error before the fix.
