Hello,

i have a problem linking a DLL with libtool and -lstdc++.
(using cygwin packages gcc 3.3.1-3 and libtool 1.5b-1)
libtool complains that
"This system can not link to static lib archive /usr/lib/libstdc++.la"

Interestingly enough, if I turn off libtool's dependency lib checking (by setting deplibs_check_method to pass_all), 
the library is built correctly, but i don't know if that is a safe approach (at least, libtool.m4 sets 
deplibs_check_method to file_magic on cygwin).

Additionally, libtool complains that "/usr/lib/libstdc++.la has been moved".
This might be caused by the libdir entry, which reads '/GCC/gcc-3.3.1-3/.inst/package-gcc/usr/lib/.' (which doesn't 
exist).
However, correcting this to /usr/lib/. doesn't solve my problem.

any comments?
Please cc me, as I'm not subscribed to this list.


cheers,
robert
