Hi,
When building with the "old" toolchain (gcc-4.6.3, glibc-2.14.1, svn
r9785), the ouput of:
echo 'int main(){}' | gcc -v -Wl,--verbose -xc -
(with PATH=/tools/bin:...)
after gcc-pass2 gives:
[...]

while the same command with the "new" toolchain gives:

See the /usr/include ???
I think we should have a look at the new switch
--with-native-system-header-dir
