Update the recognision of GCC version numbers to handle the prefix text

# figure out if gcc is available and if so we use it otherwise

# we fallback to whatever cc does on the system

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

GCCVER=`(gcc --version) 2>/dev/null | head -1`

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

  CC=gcc

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

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

  # then strip off whatever prefix Cygnus as well as GCC 3.1 prepends

  # the number with...  Hopefully, this will work for any future prefixes

  # as well.

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

  # peak single digit before and after first dot, e.g. 2.95.1 gives 29

  GCCVER=`echo $GCCVER | sed 's/\([0-9]\)\.\([0-9]\).*/\1\2/'`
