Mark Kettenis 14abd0fbf0 * configure.in: Call AC_GNU_SOURCE. Check for pread64 using
AC_CHECK_FUNCS and remove the old check for pread64.
* acinclude.m4 (AC_GNU_SOURCE): New macro.
* acconfig.h (_GNU_SOURCE): Add.
(HAVE_PREAD64): Remove.
* configure, aclocal.m4, config.in: Regenerated.

# compiler to be in ANSI C mode if it handles function prototypes correctly.
#
# If you use this macro, you should check after calling it whether the C
# compiler has been set to accept ANSI C; if not, the shell variable
# @code{am_cv_prog_cc_stdc} is set to @samp{no}. If you wrote your source
# code in ANSI C, you can make an un-ANSIfied copy of it by using the
# program @code{ansi2knr}, which comes with Ghostscript.
