+ amend treatment of infocmp "-r" option to retain the 1023-byte limit unless "-T" is given (cf: 981017). + modify comp_captab.c generation to use big-strings. + make _nc_capalias_table and _nc_infoalias_table private accessed via _nc_get_alias_table() since the tables are used only within the tic library. + modify configure script to skip Intel compiler in CF_C_INLINE. + make _nc_info_hash_table and _nc_cap_hash_table private accessed via _nc_get_hash_table() since the tables are used only within the tic library.
