negative error status: gcc vs. cl

[Daniel Lungu <lungu at nagra dot com>]

Feel like bash tcsh on Cygwin mess up with negative exit status from a cl
compiled .exe

% uname -a
CYGWIN_NT-5.0 pc 1.3.22(0.78/3/2) 2003-03-18 09:20 i686 unknown unknown Cygwin

% echo $SHELL
/bin/bash

% cat nerr.c
int main()
{
    exit (-2);
}

% gcc -o nerr-gcc nerr.c

% cl -o nerr-cl nerr.c

Positive exit status works fine from gcc and cl.

Thanks for any feedback.
