# All Makefiles use the following variables:
#
# ASTCFLAGS - compiler options provided by the user (if any)
# _ASTCFLAGS - compiler options provided by the build system
# ASTLDFLAGS - linker flags (not libraries) provided by the user (if any)
# _ASTLDFLAGS - linker flags (not libraries) provided by the build system
# LIBS - additional libraries, at top-level for all links,
#      on a single object just for that object
# SOLINK - linker flags used only for creating dynamically loadable modules
#          as .so files
# DYLINK - linker flags used only for creating shared libaries
#          (.so files on Unix-type platforms, .dylib on Darwin)
#
# Values for ASTCFLAGS and ASTLDFLAGS can be specified in the
# environment when running make, as follows:
#
#	$ ASTCFLAGS="-Werror" make ...
#
# or as a variable value on the make command line itself:
#
#	$ make ASTCFLAGS="-Werror" ...
