HOWTO: Obtaining 16-bit Visual C++ Run-Time Library Source CodeID: Q153377 
  | 
The source code for the C/C++ run-time library for 16-bit versions of Visual C++ is available to customers for informational and debugging purposes in self-extracting files. Note that the Visual C++ versions listed at the beginning of this article all use the same run-time source code.
   VCCRT1.EXE -D
   VCCRT2.EXE -D 
Each file contains roughly 1/2 the C/C++ run-time library source code. You
will need to copy and extract both files. This will require approximately
four megabytes of disk space. Several hundred files will be copied to your
disk. For more information on using the source code, please refer to the
README.TXT file included in the self-extracting files.
