Subject: w32api lower version / mess in Cygwin 1.7.18 ?
Date: Wed, 24 Apr 2013 18:22:44 +0000

Hello,

I've installed official Cygwin 1.7.18, and an application that
uses w32api does no longer compile.

Last time I used it with Cygwin 1.7.15 (where everything worked),
and /usr/include/w32api/w32api.h had:

#define __W32API_VERSION 3.17
#define __W32API_MAJOR_VERSION 3
#define __W32API_MINOR_VERSION 17

Now in Cygwin 1.7.18, that very file contains the following:

#define __W32API_VERSION 3.14
#define __W32API_MAJOR_VERSION 3
#define __W32API_MINOR_VERSION 14

Even though the newer file is more advanced than the one before
(lists more Windows and IE versions).

The DDK that comes along does not look like anything working at all:
there are tons of redifinitions (of PAGE_SIZE, to say the least), as well as the
order of header inclusions now seems to be significant (and not self-consistent
anymore):  parts of the API are aware of the NT_INCLUDED guard
(to the extent that I've figured out), parts not.

Here's just to illustrate:
In file included from /usr/include/w32api/ddk/ntddk.h:38:0,
                 from /usr/include/w32api/ddk/ntifs.h:34,
/usr/include/w32api/ddk/wdm.h:7679:0: warning: "PAGE_SIZE" redefined
/usr/include/limits.h:211:0: note: this is the location of the previous definition
In file included from /usr/lib/gcc/i686-pc-cygwin/4.5.3/../../../../include/w32api/windows.h:70:0,

So my question is basically, whoever included this into release,
did they run any checks at all prior to releasing the package(s)?

Any suggestions how to fix all this mess would be highly appreciated.

Thanks,
