#                   This version uses Keil XC16x/C16x tools under Cygwin
#
#
# CCDIRECTIVES     .. directives to pass to C166 compiler
# LIDIRECTIVES     .. directives to pass to L166 linker
# LIN_FILE         .. file containig directives to use when linking
# ASDIRECTIVES     .. directives to pass to A166 assembler
# STARTUP_CODE     .. the name of an object file to be linked to all binaries (in config.omk)

# Rules for compilation of C, C++ and assembler sources using Keil's
# (X)C16x tools. For documentation see gcc snippet.
