Autoconf seems to take care of that. This is the code generated in the 
configure script:

# Rewrite early, but we need PATH_SEPARATOR.
# The user is always right.
if test "${PATH_SEPARATOR+set}" != set; then
  echo "#! $SHELL" >conftest.sh
  echo  "exit 0"   >>conftest.sh
  chmod +x conftest.sh
  if (PATH=".;."; conftest.sh) >/dev/null 2>&1; then
    PATH_SEPARATOR=';'
  else
    PATH_SEPARATOR=:
  fi
  rm -f conftest.sh
fi


I rely on this in my autoconf/automake example for gnu-crypto.
However...
apparantly it doesn't work on cygwin. I suspect it is because I also
have to add double quotes all over the place, something like:

   jikes -classpath "address@hidden@pkg2" ...

to prevent the shell from resolving the semicolon as the "end of
command" character. It used to work on cygwin but I haven't try it for
few weeks.


However going back to the earlier Makefile discussion, I've cut and paste 
portions of the make process generated by automake/autoconf scripts for 
GCJ compilation and shared libraries. As you can see, it is not exactly 
trivial or intuitive. 
Do you really want to reinvent all of that while automake, a GNU tool 
Copyrighted by the FSF, is out there?
