Thomas E. Dickey cd858895e9 ncurses 5.6 - patch 20070812
+ 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.
