** [bugs:#1399] Lossy conversion warning with Visual C++**

In libcurl 7.37.1, there is a new warning in conncache.c Curl_conncache_add_conn when compiling for 64-bit targets with Visual Studio:
warning C4267: '=' : conversion from 'size_t' to 'long', possible loss of data
The member connection_id of struct connectdata is a long (always a 32-bit signed integer on Visual C++) and the member next_connection_id of struct conncache is a size_t, so one of them should be changed to match the other.
Please find attached a patch for lib/conncache.h that changes the size_t in struct conncache to long (the less invasive change as that variable is only ever used in a single code line).
