	Patch by Zack Weinberg.

	* math/bits/mathcalls.h: Adjust comments.  Remove gamma_r prototype.

	* sysdeps/i386/fpu/bits/mathinline.h: Make log2 only available if
	__USE_ISOC9X is defined.  Provide rint optimization.

1998-11-21  H.J. Lu  <hjl@gnu.org>

	* libio/Versions (_IO_popen, _IO_proc_open, _IO_proc_close,

	* libio/Makefile (routines): Add oldiopopen and oldpclose.
	(shared-only-routines): Likewise.

	* libio/pclose.c (pclose): Make it default for GLIBC_2.1.
	* libio/iopopen.c (_IO_proc_open, _IO_popen, popen,
	_IO_proc_close): Likewise.

	* libio/iolibio.h (_IO_new_popen, _IO_old_popen, __new_pclose,
	__old_pclose): New prototypes.

	* libio/libioP.h (_IO_new_file_jumps): Removed.
	(_IO_old_proc_jumps): Added.
	(_IO_new_proc_open, _IO_old_proc_open): New prototypes.

	* libio/oldiopopen.c: New file.
