Comment (by ruipfernandes@…):

 Indeed, changing the jam file isn't the best way.

 Answering your questions: a) yes, defining in
 <boost/config/platform/hpux.hpp> works fine; b) the reason why the
 definition is required is referred in file wchar.h, as follows:

 /*            C99 stds require WCHAR_MAX and WCHAR_MIN to be macros which
               can be used in #if constructs, hence, can't have casts
               Retaining the old macros for compatibility
  */
 #             if defined(_INCLUDE_STDC__SOURCE_199901)
 #               define WCHAR_MAX  UINT_MAX  /* max value of an unsigned
 integer */
 #               define WCHAR_MIN  0
 #             else
 #               define WCHAR_MAX  (wchar_t)UINT_MAX  /* max value of an
 unsigned integer */
 #               define WCHAR_MIN  (wchar_t)0
 #             endif
