This might break targets (if any) that still use "munch". This is a
utility that runs nm to find static constructors and generates a C
function called __main to call them all; that allows you to implement
C++ static constructors without any linker support for things like .ctors.
I've CC'd Nathan Sidwell and Nathan Froyd here; both of them are
familiar with VxWorks, which (at least the last time I used it) still
depended on munch. Nathans, does this still apply?
Oh, wait, Jan, is that the whole point of your patch? That we don't
want utilities like this to recognize these things as static constructors?
Thank you,
