Agreed.

I(we) am(are) very reluctant to some of the patch from Oyvind in
this area, for example, the one dealing with the ErroParserManager.

This is even a problem with the Spawner class, to interrupt/suspend a process
(Cygwin seems to have its own way of dealing with interruption)

So far I have no concrete/general solution when dealing with cygwin or
the case insenstive of the file system or .... etc .. etc..
