build fails w/ sed errors



Another data point.  My normal build process on windows is a cygwin/msys 
hybrid.  This worked for me a long time ago and I have never changed

On cygwin:
    cvs update -dp
    copy the maxima tree to a build location
    "sh bootstrap' in the build tree

On msys, in the build tree:
    ./configure
    make
    make check

This still works.  However, if run "sh bootstrap" under MSYS then I get 
sed errors when I run configure, suggesting that one of the files 
generated by the MSYS bootstrap process is broken.  I will investigate 
further.
