oh, I use -C for nm (i usually do that) and nothing was shown. I also used 
/usr/bin/i586-mingw32msvc-nm instead of my linux nm. With -AP, it is 
indeed shown.

i played a bit with the order and now the undefined has gone. It remains 
a:

"*** Warning: linker path does not have real file for library -luuid. 
etc..."

i passed -no-undefined to the linker but it seems that libtool is still 
not happy :/ Hence no dll is built.

ok for the ML.

talking about cross-compilation provided with mingw, the doc about setting 
it is too complicated. I have looked at http://mingw.org/node/31

you have indeed, after the download of the different files 3 paragraphs 
about gcc 4.* and updated scripts (yes, several updates...). The user (me, 
for example...) is asking himself: "what should I do ???"

if mingw provides a way to cross-compile mingw progs on linux, only one 
"official" way should be given (like gcc ports as a guy ported different 
versions of gcc 4.3 for mingw, but no official 4.3 port (well, there is 
an alpha of 4.3.0) is supported by mingw right now.

also, in that page, there are some missing links. I have:

Get [this shell-Script]
Get [this patch to math.h]

without links
