+Subject: [PATCH] Make HgfsConvertFromNtTimeNsec aware of 64-bit time_t on i386
+
+I verified that this function behaves as expected on x86_64, i386 with
+32-bit time_t, and i386 with 64-bit time_t for the following values of
+ntTtime:
+
+UNIX_EPOCH-1, UNIX_EPOCH, UNIX_EPOCH+1, UNIX_S32_MAX-1, UNIX_S32_MAX,
+UNIX_S32_MAX+1, UNIX_S32_MAX*2+1
+
+I did not verify whether the use of Div643264 is optimal, performance
+wise.
