When you have support for 16-byte alignment built into binutils, the
gcc/gfortran option -mpreferred-stack-boundary=4 [this means 2**4]
should accomplish what you requested.

I don't think so. I don't want to align the stack but data on the heap.

I don't see how gfortran will distinguish between stack and heap
alignments; perhaps your question is more complicated than you have told us.

If so I don't know why. gcc supports __attribute__((aligned(16))) why
shouldn't gfortran have something similar?
Unfortunately most people try to tell me why I don't need alignment, but
I really do need it for the DMA-Transfer stuff on Cell...

You're asking for info of in the wrong forum. Try posting to
gcc at gcc.gnu.org and fortran at gcc.gnu.org.

Ah, thats a good idea. Thanks!
