l4re compilation

Hi all,

I am trying to compile l4re run time from the snapshot (l4re-snapshot-
2014053111) using GCC 4.9 on an x86-64 machine with multilib. The 
compilation fails with not being able to find cstdio header file. I followed 
the instructions in http://os.inf.tu-dresden.de/L4Re/build.html.

I note that the fiasco kernel itself builds fine from the same snapshot.


Some debug information:
--------------------------------------------
Output of gcc -v

Output of make O=build in the src/l4 directory (of what I think maybe 
relevant parts)

Is this a problem with the GCC version? Any help is much appreciated.

Best,
