In Windows using VS 2013 : error C3861: 'sleep': identifier not found , fix Capital S

[meiry]

In the telemetry_client example
for windows there is need to change to Sleep line 114
Something like this :

#ifdef WIN32
#define sleep Sleep  
#endif

I've pushed an update to the telemetry_client that should fix this. If someone could confirm, that would be helpful.
