[Clfs-dev] Problems with 6.10. GCC-4.8.2

[Filip Bartmann]

I'm compiling CLFS after long time,
and I have some troubles with compiling GCC in chapter 6.10. I use dev
version of book.
make phase ends with:
-------------------------------------------
g++ -c -DIN_GCC    -DGENERATOR_FILE -I. -Ibuild -I../../gcc-4.8.2/gcc

-------------------------------------------

What I'm doing wrong. I have making no deviations from book.
