Description:
------------
ext/enchant/tests/dict_suggest.phpt TC fails as enchant_dict_suggest function is not compatible on Big Endian architecture.
The failure is observed at memcpy function in ext/enchant/enchant.c. 
enchant_dict_suggest function fails to return an array of suggestions, instead it returns null object.

It can be observed that the n_sugg variable is of type int(4 bytes) whereas the n_sugg_st variable is of type size_t(8 bytes).
Hence due to different memory alignment on big endian system, the memcpy fails to copy the memory blocks containing actual data.

AS a workaround, I found that by declaring data type of n_sugg as size_t instead of int, the TC passed on both, Little and Big endian system.Kindly let me know if I shall raise a PR with this changes.

PFB test result observed on Little and big endian architecture for respective TC(ext/enchant/tests/dict_suggest.phpt).
