Fails to compile on Mac OS X x64 #108

Attempting to compile on OS X High Sierra in x86-64 (config.log attached) fails with the following warning:

/Applications/Xcode.app/Contents/Developer/usr/bin/make  all-am
depbase=`echo src/hssp-nt.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\

src/hssp-nt.cpp:478:16: error: comparison of unsigned expression < 0 is always false [-Werror,-Wtautological-compare]

Removing the (seemingly unnecessary) check seems to fix the issue.

Thank you for pointing this out. In the next release, this expression will be replaced by "ix < d".
