[Mono-dev] jay "cannot open" mcs/class/System.XML/System.Xml.XPath/Parser.jay

[Dale Schumacher]

Tried a fresh build today (new install on a new Windows 7 box) under
Cygwin 1.7.9-1 using sources cloned by git.  Got the following error:

./../../jay/jay -ct < ./../../jay/skeleton.cs
/home/dalnefre/mono-dev/github/mono/mcs/class/System.XML/System.Xml.XPath/Parser.jay
>System.Xml.XPath/Parser.cs
C:\cygwin\home\dalnefre\mono-dev\github\mono\mcs\jay\jay.exe: f -
cannot open "/home/dalnefre/mono-dev/github/mono/mcs/class/System.XML/System.Xml.XPath/Parser.jay"
Makefile:80: recipe for target `System.Xml.XPath/Parser.cs' failed

Seems like this may have been reported back in September:

My searching hasn't located a cause, fix or work-around.  Suggestions please?
