I'm playing with trying to get Qt working on a wince (armv4i) device.
We've been provided a custom sdk for this device which is derived from
Window CE 6.0 Pro and I'm using Visual Studio 2008. I've created a
custom mkspec to specify the CE_SDK variable. Everything else is the
same as the wince standard armv4i 2005 sdk. I was able to run through
configure successfully, but when I compile I run across the following
error:

In the sdk there *is* an errno.h, however in zutil.h, there is
#ifdef NO_ERRNO_H
# ifdef _WIN32_WCE
/* The Microsoft C Run-Time Library for Windows CE doesn't have
* errno. We define it as a global variable to simplify porting.
* Its value is always 0 and should not be used. We rename it to
* avoid conflict with other libraries that use the same
workaround.
*/
# define errno z_errno
# endif
extern int errno;
#else
# ifndef _WIN32_WCE
# include <errno.h>
# endif
#endif
Since _WIN32_WCE is defined, errno,h does not get included and the
workaround global isn't defined. What is the proper way to work around
this?

Bill
