I think I've seen it, even used it but the name escapes me too.

Given the srcs for vfy, it would be dead simple to rename it, and make it 
look not for the $87CD of an os9 file, but for a $62CD which is the 
identifier of a C library module. Very trivial change. Maybe even make 
it automatic by using a -cs to tell it to split a C library?  And the 
srcs are on my web page or maybe even "out there".

I think for safety, if if finds a -c option, it should disable anything 
else except the s.  The rest of a C module header has different uses 
than an os9 header assumes. So disable that stuff which can modify other 
parts of an os9 modules header.
