Hmm. I don't have an include/limits.h on my build.

Anyway, neither include/limits.h or include-fixed/syslimits.h would be 
removed with the command I'm proposing. I'm currently in the middle of 
testing this on two machines. One is RH 6.2 (still in progress) and one 
is a recent-ish (last year and a half or so) version of LFS. Probably 
circa 6.3.

The command I propose is:

GCC_FIXED=`dirname $(gcc -print-libgcc-file-name)`/include-fixed &&
find ${GCC_FIXED}/* -maxdepth 0 -xtype d -exec rm -rvf '{}' \; &&
rm -vf `grep -l "DO NOT EDIT THIS FILE" ${GCC_FIXED}/*` &&
unset GCC_FIXED

All I've done is rename the variable to be a bit shorter and perhaps 
somewhat more accurate, and to change the final directory from 'include' 
to 'include-fixed'.

When it runs on the recent LFS host, the output is:

removed 
`/home/jhalfs/build/tools/bin/../lib/gcc/i686-pc-linux-gnu/4.3.2/include-fixed/asm/posix_types.h'
removed directory: 
`/home/jhalfs/build/tools/bin/../lib/gcc/i686-pc-linux-gnu/4.3.2/include-fixed/asm'
removed 
`/home/jhalfs/build/tools/bin/../lib/gcc/i686-pc-linux-gnu/4.3.2/include-fixed/linux/a.out.h'
removed directory: 
`/home/jhalfs/build/tools/bin/../lib/gcc/i686-pc-linux-gnu/4.3.2/include-fixed/linux'
removed 
`/home/jhalfs/build/tools/bin/../lib/gcc/i686-pc-linux-gnu/4.3.2/include-fixed/openssl/bn.h'
removed directory: 
`/home/jhalfs/build/tools/bin/../lib/gcc/i686-pc-linux-gnu/4.3.2/include-fixed/openssl'

Then:

root [ ~ ]# ls -l /tools/lib/gcc/i686-pc-linux-gnu/4.3.2/include-fixed/
total 12
-rw-r--r-- 1 root root 3470 2008-10-19 18:59 limits.h
-rw-r--r-- 1 root root  750 2008-10-19 18:59 README
-rw-r--r-- 1 root root  330 2008-10-19 18:59 syslimits.h


I'll post back soon when the RH 6.2 machine catches up with its output. 
It's currently building glibc in chapter 5.
