Hi Yann,

I'm trying to build a PowerPC e500 uClibc toolchain using crosstool-ng, and 
I'm consistently getting a "fatal error: fenv.h: No such file or directory" 
error at the "Installing static core C compiler" stage. I've selected gcc 
4.5.2, binutils 2.21, and uClibc 0.9.31. My host toolchain is gcc 4.6.1 
(prerelease), and binutils 2.21.51.20110523, on current Debian Wheezy 
(testing).

The full failed command line is as follows:

My .config and uClibc.config are attached. I can also provide the full build 
log if this is necessary.

Thanks for a great tool.
