Warning: g_snprintf()'s function signature has an annoying botch in it  
- the size argument is a gulong, not a gsize.

Not a problem in the UN*X and Windows ILP32 environment and in the  
UN*X LP64 environment, but it causes the Microsoft compiler to  
(correctly) warn about a conversion from a 64-bit integer to a 32-bit  
integer in the Windows LLP64 environment.  Cast sizeof - or any other  
size_t value - to (gulong) before passing it as the length argument to  
g_snprintf().
