Sorry about the delay in responding to this, just found your e-mail while 
starting to catch up on some older ones.  The tweak below fixes a bug in 
which valid syntax was not accepted by the computer.  This was followed by 
several commits that introduced that valid syntax into the source tree, 
meaning that the tree would not build with an older compiler due to the 
older compiler incorrectly rejecting it as invalid.  Ideally, commits to 
update the compiler are made, and then after some longish delay (a few 
weeks), the source code is updated to make use of new compiler features. 
In this case, the changes came in close proximity, resulting in a few more 
stubbed toes.

   Fix bug where static forward declarations weren't accepted.
   This allows us to fix non-ISO-C constructs in our kernel to legal ISO-C.
