    FWIW, Fedora core 2 works OK with this change.

Does that mean we can delete the other PROBLEMS item?
(The one about exec_shield, that is.)

The exec-shield workaround kicks in if the difference between the end of the data section and the start of the heap is greater than MAX_HEAP_BSS_DIFF which is 1 Mbyte. But MAX_HEAP_BSS_DIFF is a value I came up with when examining the exec-shield code in the Linux kernel for Fedora 2. However, there is nothing preventing a new exec- shield implementation to change this. Also, as far as I know, the workaround has only been tested on the ix86 architecture.

So I'd propose we keep it in PROBLEMS, but we could add that Emacs tries to handle exec-shield itself. A note on how to disable the randomization should be added to PROBLEMS also.
