MS Compile with MS C++

[Gossett, Mal]

Developers:   It looks as though something is broke, but not being a C++ programmer, it could be my distribution.  This is the error message I get when trying to compile under MS C++ v 6.0.  The unistd.h is not part of my INCLUDE library, so perhaps you can enlighten me.  I also removed the /WX switch from the CFLAG line, but this did not help.  I also ran the ‘vcvars32’ to no avail.  The ‘/I’ does not work either.  The file just does not exist.     Thanks   D:\openssl-engine-0.9.6c>nmake -f ms\ntdll.mak   Microsoft (R) Program Maintenance Utility   Version 6.00.8168.0 Copyright (C) Microsoft Corp 1988-1998.
