OK. This does not change the problem, sorry.

I have made it as small as possible, removed automake libtool and 
gettext to have only make and autoconf involved. Please have a look at 
it here:

        http://dar.linux.free.fr/autoconf_test.tar.gz

On several systems (Solaris 2.6, openBSD 3.6, macOS X 10.2) the
"./configure && make" fails due to the redefinition by the configure 
script of the mbtate_t type, on Linux instead it seems to work properly,
with the same compiler version.

the problem seems to be linked with the gcc C++ header files:

after    struct declaration

while with the same compiler version on linux all works perfectly 
well... 8-|
