This only affects Libtool 1.5.x -- HEAD already has the offending cases
removed.  I also found an occurrence of 'grep -E' in ltmain.in which
I've replaced with $EGREP.

I've used the following slightly more verbose ChangeLog entry and
applied to branch-1-5.

2004-2-03  Paul Eggert  <address@hidden>

        * libtool.m4 (_LT_AC_LANG_CXX_CONFIG, AC_LIBTOOL_PROG_LD_SHLIBS):
        Replace needless uses of egrep with grep as egrep may not exist,
        POSIX no longer mandates it.
        * ltmain.in: Replace use of 'grep -E' with '$EGREP -e' in case
        egrep is the only thing that exists.
