That's OK for allocating VLAs, but it's too broad for vla.h since vla.h does not 
allocate VLAs and its uses of variable-length arrays do not have the security or 
performance issues that people ordinarily think of when they think of VLAs.

I see that vla.h's comments are too terse about this, so I installed the 
attached patch to try to clarify things.
