This might be a result of the problem, too. When I run the command on W7 and W2008R2, it hangs a couple of seconds at this point, apparently running a find(1) command, and then the output starts like this: --- SNIP --- ierr=256 in command='find $HOME/local /home/corinna/bin /usr/local/bin /usr/bin /bin /mnt/c/Windows/system32 /mnt/c/Windows /mnt/c/Windows/System32/Wbem /mnt/c/Windows/System32/WindowsPowerShell/v1.0 -name '*gcc*' -exec ./xisgcc '{}' \;'!
