lint check for non-unique externals ?

[stevens at hsi.UUCP]

We develop all of our C code internally on a VAX running 4.2 and port
the finished code to, among other systems, an IBM PC.  We continually
run into the problem of the VAX accepting more characters in an
external name than Venix on the XT.  It sure would be nice if there
was a lint flag that could check for this.  It should be a flag that
lets the user specify the number of characters of uniqueness required
for externals.  Anyone done this to lint yet ?
