FreeBSD 4.3 cross compiling for arm-wrs-vxworks
>Description:
configure.in translates --target=xxx to --host=xxx and sends --with-cross-host=${host_alias} down to compilations of libraries.  Additionally, when --with-cross-host is defined, libstdc++-v3 assumes that unless you declare the target as *-*-linux* you are using newlib and overrides whatever is appropriately determined by configure.target.
>How-To-Repeat:
I am configuring as follows:

../configure --disable-shared --without-pic --prefix=/usr/wind/host/x86-freebsd --target=arm-wrs-vxworks
>Fix:
configure.in should change to set initial value as

targargs="--cache-file=../config.cache --target=${target_alias} --build=${build_alias} ${targargs}"

and case on target_alias should be removed from libstdc++-v3/configure.in and done for the appropriate case in libstdc++-v3/configure.target.
