Build error with Swig > 2.04

[esbullington]

Thanks for a great string retrieval package! Been using it with C++ and am setting it up to work with Python.

However, I was unable to build simstring for use with Python using Swig 2.04. My problem relates to the following issues, which were described in the Swig CHANGE doc for version 2.05:

2012-03-20: wsfulton
Fix #3487706 and #3391906 - missing stddef.h include for ptrdiff_t when using %import
for STL containers and compiling with g++-4.6. An include of stddef.h is now only
generated when SWIG generates STL helper templates which require ptrdiff_t. If you
were previously relying on "#include <stddef.h>" always being generated when using a
%include of an STL header, you may now need to add this in manually.

I was able to build simstring with Swig using the method recommended above: specifically, manually placing a "#include <stddef.h>" in the "export_wrap.cpp" file. I don't know Swig well enough to propose a patch which would generate this automatically.

Thanks again.

I'm using SWIG 2.0.10 and managed to solve this problem by adding -I/usr/include/sys in prepare.sh.
