Thanks for your help, but I did some search on my own and I found the
problem, effectively by looking at config.log.
The libstdc++ configure script, at some point (line 5731 and following),
tries to determine the locale model. For this it builds a test program
which tries to set the locale to the German one ("de_DE"). In my
distribution, it is possible to selectively install the locales. Thus I
installed only the ones which are of interest to me, that is French and
English. In this case, the test program fails with a SEGV, and the local
model defaults to generic (which, I assume, means only C and POSIX).
Now I installed also the German locale, and everything seems OK.
Don't you thing that there should be some notice in the doc, telling
that determining the locale model depends on installing the German
locale ? Or possibly some documentation about --enable-clocale (to the
best of my knowledge, it is not documented). Or, much better, find a
more accurate way to determine the local model. For instance, at least
(but I know it won't be sufficient), try the current locale (if any, if
not cross-compiling, and if different from C/POSIX...) when building C++
instead of forcing the German one (which appears to me a little
Süse-oriented ;-)).
