platform/OS: Intel/Windows 2000
Compiler: Microsofts's MSVC 6.0
Unix-ish Tools: Latest cygwin


Problem:
-------------
MSVC does not include the header file <unistd.h>. The "scanner.c" file
generated by "scanner.l" using flex:

(i.e. flex -vPdf_ -oscanner.c scanner.l)

creates the directive: #include <unistd.h> in scanner.c

Compiling fails due to not finding this include file...


Notes:
---------

I did search the archive and found some reference to this problem but not a
solution....


My Solution:
------------------
I found the following conditional directive code to use and compiling was
successful: 

#ifdef _MSC_VER
#include <io.h>
#define access _access
#else
#include <unistd.h>
#endif

Is this valid to use or what do you folks suggest?

Is Microsoft's <io.h> a valid replacement for the UNIX <unistd.h> header
file? 


Thanks in advance...
