[gccsdk] RePackaging using trunk GCC instead of 4.1.2

I'm in the process of modifying the autobuilder packaging to set

up the new packaging Components field.

 

Once I've done this and tested it I intend to go through the

autobuilder programs/libraries that generate packages

and update them all (or as many as I can get to build).

 

I was wondering if this would be a good time to change my

machine to use the trunk version of the compiler (4.7?)

instead of the 4.1.2 version I currently use.

 

I've a few questions to see if it seems like a good idea.

 

Is the trunk compiler stable enough to use in this way?

 

To run programs compiled with it, does it need new versions

of the Shared Unix Library?

 

To run programs compiled with it, does it need new versions

of SharedLibs?

 

Can I freely use libraries compiled with 4.1.2 with the trunk

version and visa versa?

 

Any other opinions on if this is a good idea or not?

 

Thanks,

Alan
