GNU Make FishEye/Crucible syntax highlighting.

make.def

# Basic GNU make syntax highlighting rules for FishEye/Crucible.
#
# Put this file to the <FISHEYE_INST>/syntax directory and update the
# <FISHEYE_INST>/syntax/filename.map file to contain the following lines:
#
# "**/*.mk" make.def "Makefile"
# "**/makefile" make.def "Makefile"
# "**/Makefile" make.def "Makefile"
# "**/GNUMakefile" make.def "Makefile"
#
# FishEye/Crucible needs to be restarted to have the changes take effect.
