/* +*+ SAF  Sorry about the hacks with errno; NT made me do it :(

 WinNT does define an errno.
 It is mostly a legacy from the XENIX days.

 Depending upon the version of the C run time that is linked in, it is
 either a simple variable (like UNIX code expects), but more likely it
 is the address of a procedure to return the error number.  So any
 code that sets errno is likely to be overwriting the address of this
 procedure.  Worse, only a tiny fraction of NT's errors get set
 through errno.

 So I have changed the netperf code to use a define Set_errno when
 that is it's intent.  On non-windows platforms this is just an
 assignment to errno.  But on NT this calls SetLastError.

 I also define errno (now only used on right side of assignments)
 on NT to be GetLastError.

 Similarly, perror is defined on NT, but it only accesses the same
 XENIX errors that errno covers.  So on NT this is redefined to be
 Perror and it expands all GetLastError texts. */
