#342 1.3.2 compile failure

[Dan Kokron]

I get the following compile failure while building meshlab-1.3.2
using gcc (GCC) 4.7.2 20121109 (Red Hat 4.7.2-8)
under Linux 3.7.5-201.fc18.x86_64

See possible workaround below.

Adding #include <unistd.h> to the non-WIN32 section does allow the code to build. I have no idea what the consequences are. See attached output from 'diff'.
