As far as I can determine: nothing. The only thing I can come up with is
that Eclipse calls "make" using *cmd.exe* instead of sh.exe (the latter
being used in MSYS), which of course returns Windows paths and not
MSYS/unixlike paths.. But that does not explain the rewriting: the
Makefile is not changed, so why would libtool rewrite it's files?

But the actual error is caused by the following path changes :

The working MSYS file:

dependency_libs=' /d/workspace/Danu/mingw/library/DanuBase/libdanubase.la 
-lpthread'
[snip]
relink_command="(cd /d/workspace/Danu/mingw/library/DanuStream; /bin/sh 
../libtool  --tag=CXX --mode=relink g++ -I/d/boost/include -g -Wall -Wextra 
-Wundef -Wshadow -Wconversion -Wmissing-declarations -no-undefined -o 
libdanustream.la -rpath /usr/local/lib libdanustream_la-BaseStream.lo 
libdanustream_la-ByteStream.lo libdanustream_la-DllMain.lo 
libdanustream_la-FileStream.lo libdanustream_la-StreamableObject.lo 
libdanustream_la-StreamableObjectCreator.lo 
libdanustream_la-StreamableObjectFactory.lo 
../../library/DanuBase/libdanubase.la @inst_prefix_dir@) "


The non-working Eclipse file:

dependency_libs=' D:\workspace/Danu/mingw/library/DanuBase/libdanubase.la 
-lpthread'
[snip]
relink_command="(cd D:\\workspace/Danu/mingw/library/DanuStream; /bin/sh 
../libtool  --tag=CXX --mode=relink g++ -I/d/boost/include -g -Wall -Wextra 
-Wundef -Wshadow -Wconversion -Wmissing-declarations -no-undefined -o 
libdanustream.la -rpath /usr/local/lib libdanustream_la-BaseStream.lo 
libdanustream_la-ByteStream.lo libdanustream_la-DllMain.lo 
libdanustream_la-FileStream.lo libdanustream_la-StreamableObject.lo 
libdanustream_la-StreamableObjectCreator.lo 
libdanustream_la-StreamableObjectFactory.lo 
../../library/DanuBase/libdanubase.la @inst_prefix_dir@) "

Notice the change from /d/ to d:\  in the first and /d/ to d:\\ in the
second quoted line.

The error I get is saying something about D:workspace, so I assume that
it is about the first line without the escaped \ in d:\workspace.

That is the other line I am investigating. But for now I am satisfied
with (and desperate for) every working solution ;-)

I am afraid I did not convince you, but there are more details ;-)
