[lmi] fix for Timer::inspect() on POSIX platforms

[Vaclav Slavik]

Hi,

please apply the following (or equivalent; I preferred explicit cast to
simply appending ".0" as it makes it more clear why is it done) patch:

     gettimeofday(&x, 0);

 #elif defined LMI_MSW
 #   ifdef LMI_MS_HEADER_INCLUDED
     LARGE_INTEGER z;

This deserves some explanation: on POSIX, elapsed_t is double and the
value is microseconds since the Epoch, i.e. a really large value that
doesn't fit into long int on x86/x86_64. Without the cast, the "1000000
* x.tv_sec + x.tv_usec" expression is evaluated as integer one and
overflows.
