[Patch, fortran] PR20541 - allocatable components (TR15541)

[FX Coudert]

Congratulations to Paul and Eric!

Such long and involved patch is always hard to review, but I'll give  
it a look over the week-end. I'll approve the parts I understand, and  
I will bootstrap and regtest on a couple of platforms (sparc-sun- 
solaris2.9, hppa-hpux, ia64-linux). But, with two person designing  
this patch and so much testing before submitting it, I think we  
should commit it soon to get it exposed, even if the reviewing is not  
of the standard we'd like to enforce (except for the non-insulated  
part of the patch). Opinions?

Thanks again,
FX
