When allocating a large amount function local variables the prologue uses
alloca instead of simple stack allocation.
I (from the documentation) expected -ffreestanding to turn this off but it
does not.
Is there any way to work around this (I don't have alloca implemented)
regards

This only happens when configured for a windows target, as
that's what the ABI sez.

Configure for a different target.
