Huh, that's beginning to get though...

If gcc 4 tends to warn about pointer casts which *may* discard target 
type we're probably out of luck :-(

I don't really know *why* gcc warns about this anyway.

When I do a cast, I probably *intended* to cast from e.g. "const gchar 
*" to "gchar *" as that's what the whole cast is all about. Warning 
about a cast which *might* be
wrong is odd to my eyes, as that's what a cast is about (to tell the 
compiler what the developer intends to do).

If a var is defined as:

const gchar * whatever;

and a call to a GTK1.x functions requires a "gchar *" what could you do 
anyway?


Conclusion: I would love to see all these warnings disappear on every 
compiler "we" use. I thought that I'd understand the problems on this 
task, but unfortunately the gcc 4.x compiler has a different point of 
view :-(

I would really love to see someone with more knowledge than me could 
spread some light to solve this topic?!?
