Pavel Roskin 8800ca2bbf * configure.in: AC_CANONICAL_SYSTEM moved above AM_INIT_AUTOMAKE 
to avoid a warning
* acinclude.m4: removed unused macros AC_CHECK_HEADER_IN_PATH,

dnl If the C compiler in not in ANSI C mode by default, try to add an option
dnl to output variable @code{CC} to make it so. This macro tries various
dnl options that select ANSI C on some system or another. It considers the
dnl compiler to be in ANSI C mode if it defines @code{__STDC__} to 1 and
dnl handles function prototypes correctly.
dnl
dnl If you use this macro, you should check after calling it whether the C
dnl compiler has been set to accept ANSI C; if not, the shell variable
dnl @code{ac_cv_prog_cc_stdc} is set to @samp{no}. If you wrote your source
dnl code in ANSI C, you can make an un-ANSIfied copy of it by using the
dnl program @code{ansi2knr}, which comes with Ghostscript.
dnl @end defmac
dnl Unixware 2.1 defines __STDC__ to 1 only when some useful extensions are
dnl turned off. They are on by default and turned off with the option -Xc.
dnl The consequence is that __STDC__ is defined but e.g. struct sigaction
dnl is not defined. -- Norbert
