--- Comment #3 from mail@kirill-mueller.de 2013-11-13 04:31:53 CST --- Thanks for your extensive analysis, the messages from this list got lost in my spam folder :-(
Just to clarify, it's "Rtools", not "Rstudio". I've got to ask the people over there if they might consider upgrading to a more recent cygwin.
Can anything be done on the Wine end to work around this?
