Can't build latest emacs on MSW + CRLF display issue

[Vincent Belaïche]

Hello,

I have been trying to build the latest emacs on MSWindowsXP + MinGW and
I came across the following issues:

- during the build I get the following error message

In toplevel form:
url/url-proxy.el:24:1:Error: Symbol's function definition is void: cl-member


- during the make-install I get the following error message

gcc -o oo-spd/i386/profile.exe  -gdwarf-2 -g3    oo-spd/i386/profile.o 
../lib/oo-spd/i386/libgnu.a oo-spd/i386/ntlib.o   -ladvapi32
mingw32-make.exe[1]: Leaving directory 
`C:/Programme/GNU/installation/emacs-install/emacs/trunk/lib-src'
mingw32-make.exe[1]: *** No rule to make target 
`../lisp/international/mule.elc', needed by `DOC'.  Stop.
mingw32-make.exe: *** [all-other-dirs-gmake] Error 2


Anyway, the build has gone far enough so that I have an emacs.exe with
the latest source, and it confirmed a problem which I had with my
previous build, the display of ^M at ends of lines seems buggy:

Here are two pictures:

http://savannah.gnu.org/bugs/download.php?file_id=28919
http://savannah.gnu.org/bugs/download.php?file_id=28920

Both pictures concern visiting info files, but the first one (cr.info)
has the ^M hidden, and the second one (bbdb.info) has the ^M shown.

My feeling is that there is some inconsistency, but maybe I
misunderstood the criterion that triggers ^M hiding.

Both info files have consistent CRLF endings which I checked with the
attached eol_status.cpp tool.

I must say also that I met a problem on bbdb.info which then I could
never reproduce: at some point of time it was displayed w/o the ^M at
for almost the whole file except in the last few tens lines where the ^M
endings were displayed.

VBR,
   Vincent.
