XWin fails to start again (previously reported half a year ago or so).
Thanks for following up on this.
The command issued by a shortcut is
C:\cygwin64\bin\run.exe --quote /usr/bin/bash.exe -l -c "cd;
/usr/bin/startxwin"
Upon starting the shortcut, there is some disc acitivty, but no window
opens, and no XWin processes show up (according to the later-called Task
Manager).
No files in the directory /var/log/xwin are updated.
The file C:\cygwin64\run.exe.stackdump is generated, containing
Stack trace:

Achim,
Not sure if this is the cause of this problem, but after a bit of
staring at file_exists_multi(), I notice that run2_fileExits() doesn't
initialize t when it returns FALSE, so perhaps the following is a good idea?
diff --git a/src/run.c b/src/run.c
