Hi Jim,

A while ago Linux From Scratch added the '--without-included-regex' flag to grep's configure invocation in order to fix the behaviour of 'grep -i' (see http://wiki.linuxfromscratch.org/lfs/changeset/8688).

The latest snapshot passes all tests (apart from one skipped pcre test as we don't install pcre in LFS) without using that configure switch so I assume it's safe to drop now, especially given the massive amount of work Paolo and yourself have made to this area recently?

I'll note that the latest snapshot thinks that Glibc-2.11.1 still doesn't provide a working re_compile_pattern function. I may take a look and see where about's the configure test for this feature is failing, unless you know off-hand about outstanding Glibc bugs in this area? The reason I ask is that I'm wondering what your preference for distributors is; 1) use Glibc if possible, 2) use the internal lib/regex.c at all times or 3) you don't care and are happy to support either?
