# Canonicalize a name into a C identifier.  White space and a few other  junk #
# characters  are stripped out, then strings of various non-alfanum chars are #
# replaced with a single underscore.   We  also  do  assorted  shortening  to #
# regularize  some names.  This routine is called by the "icd-c", "msg-h" and #
# "mib-t" programs, to canonicalize the  various  names  that  they  generate #
# from their input files.                                                     #
