[msys] strip out cygwin paths

gistfile1.sh

#
# Strip out cygwin paths from your PATH. Assumes that your cygwin directories
# have the word cygwin in their names - if not, change the regex pattern
# appropriately.
#
# Useful for users who are using both msys/mingw and cygwin - put this in your
# ~/.profile so that msys doesn't use them.
#
export PATH="$(echo -n $PATH | awk '
	BEGIN { RS=":"; output="" }
	!/cygwin/ { output = (output == "") ? $0 : output":"$0 }
	END { print output }
')"
