thats fair.

ok, here's what I've done.  I still don't understand exactly whats going
on, but maybe someone else will:

conftest.make has:

# a test makefile
all:
        echo 'ac_maketemp="${MAKE}"'
        echo 'ac_maketemp=" ${MAKE} "'
        echo ${MAKE}
        echo "${MAKE}"
        echo '${MAKE}'
        echo 'foo="c:"'

#end of conftest.make

% /usr/bin/make -f conftest.make
ac_maketemp="/usr/bin/make"
echo 'ac_maketemp=" /usr/bin/make "'
ac_maketemp=" /usr/bin/make "
echo /usr/bin/make
/usr/bin/make
echo "/usr/bin/make"
/usr/bin/make
echo '/usr/bin/make'
/usr/bin/make
echo 'foo="c:"'
foo="c:"

/* Everything looks fine there */

% /cygdrive/c/mingw/bin/make -f conftest.make
echo 'ac_maketemp="c:/mingw/bin/make.exe"'
ac_maketemp=:/mingw/bin/make.exe"echo 'ac_maketemp=" c:/mingw/bin/make.exe "'
ac_maketemp=" c:/mingw/bin/make.exe "
echo c:/mingw/bin/make.exe
c:/mingw/bin/make.exe
echo "c:/mingw/bin/make.exe"
c:/mingw/bin/make.exe
echo 'c:/mingw/bin/make.exe'
c:/mingw/bin/make.exe
echo 'foo="c:"'
foo=:"

/* this is doesn't look good.  even echo 'foo="c:"' gave strange results */


% cp /cygdrive/c/mingw/bin/make.exe .
% ./make -f conftest.make
echo 'ac_maketemp="C:/cygwin/tmp/make.exe"'
ac_maketemp=\C:/cygwin/tmp/make.exe"
echo 'ac_maketemp=" C:/cygwin/tmp/make.exe "'
ac_maketemp=" C:/cygwin/tmp/make.exe "
echo C:/cygwin/tmp/make.exe
C:/cygwin/tmp/make.exe
echo "C:/cygwin/tmp/make.exe"
C:/cygwin/tmp/make.exe
echo 'C:/cygwin/tmp/make.exe'
C:/cygwin/tmp/make.exe
echo 'foo="c:"'
foo=:"


/* same strangeness */

Don't know if this helps anyone, I know I'm still at a loss.
