This disables Borland warning 8027 while compiling KWSys source files.
It provides no useful information.

All KWSys C symbol names begin with the KWSYS_NAMESPACE defined at
configuration time.  For ease of editing we write canonical names with
the prefix 'kwsys' and use macros to map them to the configured prefix
at preprocessing time.  In the case of standalone KWSys, the prefix is
'kwsys', so the macros were previously defined to their own names.

We now skip defining the macros in the identity case so that the final
symbol names are never themselves macros.  This will allow the symbols
to be further transformed behind the scenes to help linkers in special
cases on some platforms.

COMP: Second try getting rid of Microsoft deprecation warnings. This time tested from KWStyle with vs8 to make sure the warnings are really gone. Remove the deprecation defs from CMakeLists and guard the defs in the header so we do not redefine them if they are already defined.

COMP: Suppress Microsoft deprecation warnings when building kwsys .c and .cxx files. This way, other projects that include kwsys will not see the warnings in kwsys .c and .cxx files, but they can still see the warnings in their own source files if they want to...

ENH: Separate the notion of a request for LFS and its availability.  Allow user code to block definitions of LFS macros.  Added framework to give error if sys/types.h is included before this header when LFS is requested (currently disabled).

ENH: Moved kwsys_ns and kwsysEXPORT macros to Configure.h in the case of building a kwsys source file.  This allows more than one header to be included in a kwsys source file without redefining the macros.

ENH: Added wrappers around the std stream headers to make them look like ansi streams on all platforms.
