# the kludgificacious method of defining a pattern rule to build files
# matching patterns we are pretty damn sure will only match the particular
# files we have in mind. To be so damn sure, we use the silly names
# RPC_*.c and the pattern R%C_*.c because using __*.c and _%*.c (or any
# other useful pattern) causes the rule for `host_info' to also match
# `xxx_host_info', and analogous lossage.

# While we're at it, we figure out the imports used by %.defs and give them
# as dependencies of the object files for the generated RPC_*.c files.
