Rather than bemoaning the situation, perhaps the thing to do is overcome it.
The shell file below may be a start on doing so.  If, on a 4.1bsd system,
you name it "reborn" and then use the command
	reborn filename
where "filename" is the name of a Bourne-style C program,
a "more-traditional" version of the source code is written to the standard
output.

The script below is a quick hack, so expect the worst--little testing was done.
Surely a more portable and otherwise improved version can be created.
Is doing so worth it?  Is anyone up to it?
