Consistent, random GPFs? Rebuild all C9 binaries!

Bob Z got some attention with a posting in the newsgroups:

Subject: consistent random GPFs

Note to all:

The FILE structure used internally changed in C9, so any 3rd party tool that 
works with FILEs must be rebuilt. If you use any 3rd party binary that works 
with FILEs (or your own binary) that wasn't rebuilt with the C9 compiler you 
can expect consistent random GPFs.

In other words, any code that declares a FILE structure must be rebuilt for C9.

But this only reinforces a previously stated maxim: All binaries must be rebuilt for C9!

The bit that got everyone's attention was "consistent, random GPFs." 

Bob later indicated the changes are purely internal - no developer code needs updating (only recompiling). The structural changes were needed for future support for non-Latin characters.
