We use constructs such as the following:

bash:
====

if [[ $(uname -s) = CYGWIN_NT* ]]
then
	# handle NT/2000
else
	# handle 9X/ME
fi

sh:
==

case `uname -s` in
CYGWIN_NT*)
    # handle NT/2000
    ;;
*)
    # handle 9X/ME
    ;;
esac

make:
====

ifeq ($(findstring CYGWIN_NT, $(shell uname -s)), CYGWIN_NT)
    # handle NT/2000
else
    # handle 9X/ME
endif

> Also, it relies on the existence of uname of course...

Which is a reasonable dependency -- at least for us.
