[bug-gawk] gawk 4.1.0 fails to build on Mac OS X 10.6.8

[Larry Baker]

gawk 4.1.0 fails to build on Mac OS X 10.6.8:

Undefined symbols:

  "_history_list", referenced from:

      _do_save in debug.o

      _serialize in debug.o

ld: symbol(s) not found

history_list() does not exist in Mac OS X /usr/include/readline/readline.h.

Samba already knows about this (from http://ftp.samba.org/pub/unpacked/samba_3_current/source4/lib/smbreadline/readline.m4):

# not all readline libs have rl_event_hook or history_list

gawk 4.0.2 works fine.

Straightforward config: ./configure, make.
