Fixes some cases where clang complains about loss of integer precision.

Plus fixes call to abs that was considered ambiguous.

I may be missing something here, but I'm still getting the same build error from abs that was considered ambiguous on lucid-x64: https://gist.github.com/andrew/30eaff7e65e5e4fd0f65

../libsass/utf8_string.cpp: In function 'size_t Sass::UTF_8::normalize_index(int, size_t)':
../libsass/utf8_string.cpp:111: error: call of overloaded 'abs(int&)' is ambiguous
/usr/include/c++/4.4/cmath:94: note: candidates are: double std::abs(double)
/usr/include/c++/4.4/cmath:98: note:                 float std::abs(float)
/usr/include/c++/4.4/cmath:102: note:                 long double std::abs(long double)
make: *** [Release/obj.target/binding/libsass/utf8_string.o] Error 1

Upgrading glibc would fix it, but then the binary won't work on heroku, which uses glibc-2.11

Any suggestions?

[kornelski]

Hmm, do you think cast to double would be better?

[andrew]

@pornel yeah I just tried that out and it builds cleanly for me
