Parse version numbers prefixed with text (egcs does that, even with

GCCVER=`(gcc -dumpversion) 2>/dev/null`

if [ "$GCCVER" != "" ]; then

  CC=gcc

  # then strip off whatever prefix egcs prepends the number with...

  # Hopefully, this will work for any future prefixes as well.

  GCCVER=`echo $GCCVER | sed 's/^[a-zA-Z]*\-//'`

  # Since gcc 3.1 gcc --version behaviour has changed.  gcc -dumpversion

  # does give us what we want though, so we use that.  We just just the

  # major and minor version numbers.
