Porting gcc 4.x on tangent A4

[Giuseppe Monteleone]

Hi all

I have need to compile code for an old ARC tangent A4 core.
1) Gcc 3.x does support ARC Tangent-A4
2) Gcc 4.x dose support ARC Tangent-A4

if answer is 'not' for both question i will try to introduce code in 
arc.md and arc.c files to compile code for ARC Tangent-A4. Is this an 
hard task ?

Thanks
