WinNT/CVS/^M prob

[Vardhan Varma]

using windowsnt4.0 + mingw + cvs from cvsnt.org.
does this cvs handles cr/lf issues properly ??

first i get emacs/nt/makefile.w32-in with additional ^M,
which i had to be manually removed or mingw's make cries.
(looks like cvs copy is wrong, can somebody with unix od it
to check if line ends in 0d0d0a , 0d0a or 0a )

and make bootstrap on entering liem, says:
Converting h:/PersonalWork/CVS-SOURCES/emacs/leim/CXTERM-DIC/4Corner.tit to 
quail-package...
Invalid ENCODE: value in TIT dictionary

again a case of BIG5^M being seen by code !!

My Question(s):
        which is Preferred set of tools in MS Env? ..
                1. Mingw / Cygwin / MSVC ?
                2. which precompiled cvs ?
                
Also:
        some of the things in Win  makefile could have been done better,
        if i eventually make a patch, whom do i share it with ?
--TIA
