# JOE syntax highlight file for C and C++
# Improved version by Matti 'ccr' Hämäläinen, based on original from Joe v3.1
#
# 2005-01-24
# - Format string handling fixed and improved
# - Non-standardly broken preprocessor tokens are highlighted as 'Bad'
# - Syntax parsing buffer increased to avoid problems with long comments
# - Added some missing C++ keywords
# - Added highlighting of GLib base types

# Set a fairly long buffer to avoid problems
