Q61304: CL: Error Output Not Redirected in Certain Cases

When using the C 6.00 CL command-line compiler under DOS with the
following options

   /B1 C1L.EXE /Zi

the output is not redirected properly (using the DOS stdout redirect
">").

The following code example reproduces the problem:

void main(void)
{
  int i
}

Compile using the following command line (assuming you save the above
in a file called FOO.C):

   cl /B1 C1L.EXE /Zi foo.c > foo.out

The above program contains an error at Line 3 (no semicolon), and the
following error should be generated and sent to the file BUG.OUT:

   foo.c(4) : error C2059: syntax error : '}'

This error text never appears in the file FOO.OUT.

This problem can be worked around by omitting the /Zi option from the
command line, or omitting /B1 C1L.EXE.

Microsoft has confirmed this to be a problem in C version 6.00. We
researching this problem and will post new information here as it
becomes available.
