Update to 0.6.6:

* Version 0.6.6 (released 2006-08-23)

** Instead of AX_CREATE_STDINT_H, use the stdint gnulib module, for idn-int.h.
This solves building on some HPPA systems.  Note that the generated
idn-int.h is specific to the build environment that libidn was built
under, and is not generally usable by any other compiler (if any) on
the host.  This was true before too.

** Update gnulib files.

** API and ABI is backwards compatible with the previous version.
