If the current tree really builds 100% with GCC 4.3.2 or you (or someone else) could provide patches for getting it to work, the update should be done as soon as possible (but after 0.3.7 :P)
I use GCC 4.3.2 and new binutils for about a month without difficulties; if you need any patches then please email me.
Of course, I do not insist on including it in RosBE.
Best wishes, Dmitry
