I was using Microsoft C, and had a program that used command line
arguments and read the standard input.  When I specified:

    command arg1 arg2 ... argn-1 < filename

The argc variable reflected the presence of the filename.  
i.e. it had the value n+1.
When I specified:

    type filename | command arg1 arg2 ... argn-1

it was not indicated, i.e. it had the value n.  I think this must 
be a compiler bug.  -David-
