Windows SDK is not found

[Regina Henschel]

Hi all,

trying to configure on WinXP in cygwin with MSVC Express 2008

I get the error
checking for Windows SDK... configure: error: Some (all?) Windows SDK 
files not found, please check if all needed parts of the  Windows SDK 
are installed.

I have tried also with
--with-windows-sdk-home="/cygdrive/c/Programme/Microsoft SDKs/Windows/v6.0A"

The result of
  $ ./oowintool --windows-sdk-home
has been
/cygdrive/C/Programme/Microsoft SDKs/Windows/v6.0A

I did not had this problem in November and have not changed the 
environment. What has changed?

Kind regards
Regina
