/* The proper format of this file:

1. All #undef statements that are changed by configure should go together,
   BEFORE the inclusion of the s&m files, and need to be bracketed by
   #ifndef WIN32_NO_CONFIGURE.  There is currently only one exception to
   this: SYSTEM_TYPE.

2. All other code, except for the things that may be referenced in s&m
   files (there is very very little of this) need to go AFTER the inclusion
   of s&m files.

Together, this ensures that the s&m files can override configure
determinations as necessary, and we will properly notice this.

/*
This file now serves both as config.h.in and simply as config.h under
Windows NT.  Under Windows NT, there is no configure script that
operates, so it is necessary for the relevant constants to be set
manually, either by the user (for user options) or in s/windowsnt.h.

Formerly, under NT there were three different places where constants
were defined -- nt/config.h, nt/xemacs.mak and s/windowsnt.h; now only
the latter two are used. (This separate config.h was a hassle because
it required constant synchronization between it and src/config.h.in.)
Since the options that are substituted by configure are written in
config.h.in with #undef, it is easy to make this file serve as
config.h under Windows NT.  Options that are set by the user are
specified in the file config.inc.samp, which is included by xemacs.mak
\(the makefile) and used to set command-line options to the
compiler.  The sorts of options that relate to the system and not to
the user and which are normally auto-determined by configure are set
in windowsnt.h.

What this means is that a little more care has to be taken in the way
things are arranged in config.h.in.  In particular:

-- Everything that is written with a #undef should be bracketed by
   #ifdef WIN32_NO_CONFIGURE, and these #ifdefs should in general be
   grouped together as much as possible.

-- Things that are not #undefs should not go inside this bracketed
   #ifdef, because these things typically set constants based on other
   constants and those latter constants may be set elsewhere under
   Windows NT.

-- Any #ifdefs that depend on constants that may be set in windowsnt.h
   need to be moved after the point at which this file is
   included. This applies for example to the error checking macros.

/* About __STDC__: Different compilers differ wrt __STDC__.  Sunpro C
    defines it, but its value is 0 unless we disable non-ANSI extensions.
    VC++ doesn't define it at all unless we disable non-ANSI extensions.
    But these compilers are all ANSI-compliant. So don't go testing
    __STDC__ anywhere except in code that runs only on known
    compilers. --ben

    Jamie wrote the following:

    [[ The ANSI standard says that defining __STDC__ to a non-zero value
    means that the compiler conforms to that standard.  The standard
    requires certain header files and library functions to be present.
    Therefore, if your compiler defines __STDC__ to non-0 but does not have
    ANSI headers and the ANSI library routines, then your compiler is
    buggy.  Conversely, an ANSI-conforming environment (which has both the
    ANSI headers and library routines, i.e., stdlib.h and `memmove') does
    not necessarily define the STDC_HEADERS flag.  Lucid Emacs requires an
    ANSI compiler.  Therefore, there is no need to consult the abominable
    STDC_HEADERS flag.  -- jwz ]]

    In reality, we should not be testing STDC_HEADERS at all except
    possibly in code we're purposely keeping in close sync with FSF code.
    STDC_HEADERS should be defined on *ALL* compilers.
