Thank you, to fix my problem, I just added #ifndef _LIBC_LIMITS_H_ #include "/LFS2011/include/limits.h" #endif on top of /LFS2011/lib/gcc/i586-pc-linux/4.5.2/include-fixed/limits.h I tried to understand why (GCC) limits.h is into include-fixed, without success. I found Ian message here : http://gcc.gnu.org/ml/gcc/2007-12/msg00095.html but my glibc is not buildt with "-nostdinc" option.
