#14 extern "C" compiler error

[Peter Kuemmel]

wordrec/tface.cpp:

#ifdef __UNIX__
#include <unistd.h>
#endif

this system header moves some symbols into

extern "C" {
...
}

therefore the compiler error

../cutil/globals.h:46: error: previous declaration of ‘int optind’ with ‘C++’ linkage
../ccutil/getopt.h:23: error: conflicts with new declaration with ‘C’ linkage
../cutil/globals.h:47: error: previous declaration of ‘char* optarg’ with ‘C++’

The attached patch fixes this and a similar problem.
