Error while building LO on Windows

[Ulrich Kitzinger]

Hello,

I am trying to build Libre Office on Windows, as described in 
http://wiki.documentfoundation.org/Development/BuildingOnWindowsWithCygwinAndMSVCExpress. 
During "instsetoo_native" I get the error:

I suppose this is because the ddf-file libreoffice1.ddf contains the lines:

"LibreOffice\native\zip\en-US_de\00\presenter-screen_oxt\help\en-US\caption\com.sun.PresenterScreen-windows_x86%2Fpresenter.xhp" 
com2.sun.PresenterScreen_windows_x86%2Fpresenter.xhp
"LibreOffice\native\zip\en-US_de\00\presenter-screen_oxt\help\en-US\content\com.sun.PresenterScreen-windows_x86%2Fpresenter.xhp" 
com3.sun.PresenterScreen_windows_x86%2Fpresenter.xhp

But only for that file, presenter.xhp. All other entries are without 
"%2F", for example:


"LibreOffice\native\zip\en-US_de\00\presenter-screen_oxt\help\en-US\help.db_" 
help1.db_
"LibreOffice\native\zip\en-US_de\00\presenter-screen_oxt\help\en-US\help.ht_" 
help1.ht_

Any hints, what's wrong?

Many thanks,
Ulrich
