According to Stepan Kasal on 4/3/2008 9:48 AM:
| But AC_PROG_GREP wants grep which supports multiple -e options and
| stops with an error if there is none available.
| Is that requirement really necessary?  Does a "usual" configure
| script really need it?

Probably not - at least, on inspection, neither autoconf nor coreutils
used 'grep -e'.

|
| If not, could this requirement be relaxed somehow?

Sounds reasonable to me.  But I think it is a bit too late to experiment
with this for 2.62; we'll have to save it for after the release.

|
| The reporter has actually expirienced this when building GNU grep on
| LunxOS.  (Well, I can only guess that he tried to build GNU grep
| because another configure script has told him that none of the
| supplied grep binaries is usable.  ;-)
|
| In case the requirements for grep are not relaxed in Autoconf itself,
| shouldn't GNU grep contain a workaround, eg. a modified definition of
| AC_PROG_GREP?

That sounds like a good idea for the grep package, at any rate.
