19 # Sub-makefile for sunrpc portion of the library.
25 # The code in this subdirectory is taken from Sun's RPCSRC-4.0
26 # distribution with some additional changes from the TI-RPC package
27 # which is also available from Sun. The files are heavily changed to
28 # compile cleanly and to fit in the GNU environment. All the code
29 # from Sun's rpc, etc, and rpcgen subdirectories is in this directory;
30 # the rpc subdirectory contains only the header files. Other than
31 # that, several files were renamed so as not to exceed 14-character

35 # clnt_generic.c -> clnt_gen.c
