GDC on psptoolchain

[John Grindstaff]

Thanks very much. That actually worked and libgphobos.a appeared where 
it should (in psp next to libiberty, libc++ or whatever).

Are you using garbage collection without calling Phobos's Cmain 
function? I thought it inits GC with gc_init() so how is that possible?

I wonder if it is possible to write a C-source function wrapper around 
the PSP_MODULE_MACRO so that one could use a D main function (as normal)?
