One small issue with the 'libstdc++' libs not being put in
'sys-root/usr/lib'.  Not a big deal if just using C.


Yes, these end up in $PREFIX/arm-linux/lib instead of (as I expected)
$PREFIX/arm-linux/sys-root/usr/lib, just like libgcc_s, libsupc++ and
libiberty.  I have no idea why.  Does anyone on the list know the
rationale behind this?


Nope.  I bet the libstdc++ developers just haven't cottoned on to
gcc's --with-sysroot configure option yet.


IMO, gcc's / libstdc++'s behavior is correct, because it treats
sys-root as read-only directory and puts all generated files (headers,
libs etc.) into its private directories.
libstdc++ and its headers are such private files.


Thanks for the explanation!
