I just built gcc 4.8 and tried it with code that compiles OK with 4.7

bits/c++config.h: No such file or directory

This is from a file that includes cstdint. File c++config.h definitely
is produced and exists under /bits for each multilib in the 4.8 install
directory but it is not being found by the compiler. I have not tried
using a -I <path to c++config.h> on the command line because it was not
needed when compiling with g++ 4.7 and earlier when including cstdint.
Some possibly relevant g++ command lines options I am using are:
-mthumb -mcpu=cortex-m3 -std=c++0x
I can provide more details if necessary.
Thanks,

To fix this I copied all files from
<prefix>/arm-none-eabi/include/c++/4.8.1/arm-none-eabi/bits/ to empty
directory here <prefix>/arm-none-eabi/include/bits/
Not sure if this is right or why it is needed but now file c++config.h
is found and compiles succeed with 4.8.
With 4.7 the directory <prefix>/arm-none-eabi/include/bits/ is also
empty and does not require that files be copied to it.
