AnachronautandClaude Opus 5 ca34e077ad Add sbex.h, which was never committed 
The loadable program format's header has been in the working tree since
the loader was written and has never been in the repository: the gitignore
rules matched Source/Assembler as a directory, so it was silently
untracked. Anything cloning this repository could not build it, because
secondPass.c includes this file.

This is the failure the previous commit describes, having already happened
once without being noticed.
