I launch `configure.bat' under cmd.exe
Then I launched `mingw32-make.exe -f makefile.woextractrlm bootstrap'
both under MSYS bash and under cmd.exe, and I get the same result in
both cases.

Note that changing the shell between configure and build is not an odd
idea of mine, but it is something that is kind of suggested as possible
in the nt/INSTALL file :
-----
from a Unixy shell prompt:

cmd /c configure.bat

I have just made a trial, and it works. I prepared a file temp.in.txt
with a mixture of DOSy and UNIXy EOLs, and I run the one-liner:

under unixy shell:

sed "s/\r?$//" temp.in.txt> unix.temp.ou.txt

under dos shell:
sed "s/\r?$//" temp.in.txt> dos.temp.ou.txt

After this, both unix.temp.ou.txt and dos.temp.ou.txt have a uniform end
of line. Please see the attached files.
