* __scm.h: move libguile/scmconfig.h include up to the top, so

Browse source 
we're sure to pick up any critical defines like _GNU_SOURCE early.
#include <limits.h> removed in favor of scmconfig.h inclusion when
appropriate.  STDC_HEADERS based inclusion of stdlib.h,
sys/types.h, stddef.h, and sys/stdtypes.h removed in favor of
scmconfig.h inclusion when appropriate.  Various Win32 related
definitions removed in favor of scmconfig.h inclusion when
appropriate.
(HAVE_UINTPTR_T): definition removed (see NEWS).
(SIZEOF_PTRDIFF_T): definition removed (see NEWS).
(HAVE_LONG_LONGS): definition removed (see NEWS).
(HAVE_LONG_LONG): definition removed (see NEWS).
(HAVE_PTRDIFF_T): definition removed (see NEWS).

/**********************************************************************
This file is Guile's central public header.
When included by other files, this file should preceed any include
other than __scm.h.
Under *NO* circumstances should new items be added to the global
namespace (via adding #define, typedef, or similar to this file) with
generic names. This usually means that any new names should be
prefixed by either SCM_ or GUILE_. i.e. do *not* #define HAVE_FOO or
SIZEOF_BAR. See configure.in, gen-scmconfig.h.in, and
gen-scmconfig.c for examples of how to properly handle this issue.
The main documentation is in gen-scmconfig.c.
"What's the difference between _scm.h and __scm.h?"
_scm.h is not installed; it's only visible to the libguile sources
themselves.
themselves, and it includes config.h, the private config header.
__scm.h is installed, and is #included by <libguile.h>. If both
the client and libguile need some piece of information, and it
doesn't fit well into the header file for any particular module, it
should go in __scm.h. */
