  • configure.ac 

    From 28ee83c1f4f3901bbfd0316320006b3bbfaf8b42 Mon Sep 17 00:00:00 2001

Subject: configure.ac cleanups

Remove tests whose results are not used:
- AC_CHECK_HEADERS of unistd.h, fcntl.h, sys/time.h, sys/types.h
- AC_HEADER_MAJOR
- AC_HEADER_TIME
- AC_HEADER_DIRENT
- AC_CHECK_FUNCS of isascii, statfs, sysconf, tcgetattr,
                    tcsetattr, ftruncate
- AC_FUNC_STRCOLL

AC_C_CONST is obsolete, today it is safe to assume all C compilers
support at least C89.

The INTERACTIVE UNIX that needed AC_ISC_POSIX is long dead.
