Description

The configure can't set-up the Makefile with gnuiconv support because the system header "endian.h" is missing on these systems (AIX, HP-UX, Sun Solaris).
I made an experiment removing the check for endian.h in configure, then change the source of util/Transcoders/IconvGNU/IconvGNUTransService.cpp in this way:

#if HAVE_ENDIAN_H
#include <endian.h>
#elif HAVE_MACHINE_ENDIAN_H
#include <machine/endian.h>
#else
#include <arpa/nameser_compat.h>
#endif

The header "arpa/nameser_compat.h" contains workaround definitions of LITTLE_ENDIAN, BIG_ENDIAN and BYTE_ORDER.
The compilation of Xerces-C library finished with success, and my little test program works fine (convert file from cp1251 encoding to UTF-8).

I think the fix of it is not big deal. There is possible to use the header "arpa/nameser_compat.h" which exists on all UNIX machines, or use some specific header of Xerces-C library.
