	* eval.c (SCM_APPLY): For scm_tc7_subr_2o, throw wrong-num-args on 0
	arguments or 3 or more arguments.  Previously 0 called proc with
	SCM_UNDEFINED, and 3 or more silently used just the first 2.

	* fports.c, ports.c (ftruncate): Use "HAVE_CHSIZE && ! HAVE_FTRUNCATE"
	for chsize fallback, instead of hard-coding mingw.  Mingw in fact
	supplies ftruncate itself these days.

	* ports.c (fcntl.h): Can include this unconditionally, no need for
	__MINGW32__.

	* ports.c (truncate): Conditionalize on "HAVE_FTRUNCATE && !
	HAVE_TRUNCATE" so as not to hard-code mingw.  Use "const char *" and
	"off_t" for parameters, per usual definition of this function, rather
	than "char *" and "int".  Use ftruncate instead of chsize.  Check for
	error on final close.

	* numbers.c (scm_log10): Check HAVE_CLOG10, clog10() is not available
	in mingw.

	* posix.c (scm_execl, scm_execlp, scm_execle): Cast "const char *
	const *" for mingw to suppress warnings from gcc (which are errors
	under the configure default -Werror).  Reported by Nils Durner.

	* _scm.h (scm_to_off64_t, scm_from_off64_t): New macros.
	* fports.c (scm_open_file): Use open_or_open64.
	(fport_seek_or_seek64): New function, adapting fport_seek.
	* fports.c, fports.h (scm_i_fport_seek, scm_i_fport_truncate): New
	functions.
	* ports.c (scm_seek, scm_truncate_file): Use scm_i_fport_seek and
	scm_i_fport_truncate to allow 64-bit seeks and truncates on fports.

	* ports.c (scm_truncate_file): Update docstring per manual.

	* numbers.c, numbers.h (scm_log, scm_log10, scm_exp, scm_sqrt): New
	functions.
