Re: Couldn't build libstdc++ (configure fails) (was Incomplete building libstdc++ 2.91 with gcc 2.95.2)

[Frédéric L . W . Meunier <0 at pervalidus dot net>]

OK, I did what Alexandre Oliva wrote at
http://gcc.gnu.org/ml/libstdc++/2000-11/msg00466.html

Then it complained:

updating cache ./config.cache
loading cache ./config.cache within ltconfig
/usr/local/src/gcc-2.95.2/libstdc++/../ltconfig:
/usr/local/src/gcc-2.95.2/libstdc++/../ltcf-c.sh: No such file or directory
configure: error: libtool configure failed
Configuring in i686-pc-linux-gnu/libf2c

So I also copied the ltcf* files to /usr/local/src/gcc-2.95.2/
and issued a make all-target-libstdc++ after the build.

Now I get the following error (FWIW I'm using glibc 2.2):

BTW, is this normal with 2.95.2?
checking for GNU C++ __complex__ support... buggy
