non-GNU sed complanits from Libtool CVS

[Robert Boehne]

Hello,

I'm seeing this sed invocation spitting out complaints
on any platform not using GNU sed, i.e.  OS X, FreeBSD, IRIX, Tru64
to name a few.  Any idea why?

lt_compile=`echo "$ac_compile" | sed \
   -e 's:.*FLAGS\}\? :&$lt_compiler_flag :; t' \
   -e 's: [^ ]*conftest\.: $lt_compiler_flag&:; t' \
   -e 's:$: $lt_compiler_flag:'`

Here is a sample of the error messages when running configure
under Mac OS X:
