# SYNOPSIS
# ========
#
# ::
#
#  $ Fcheck_archfile.sh
#
#
# DESCRIPTION
# ===========
#
#
# Check the choice of the compiler.
# Three cases :  
#
# - There was a previous choice
# - A new one has be specified, we use this one
# - No information, exit
#
# We use TOOLS/COMPILE/arch.fcm to see if something was chosen. 
#
# EXAMPLES
