glibc/math/Makefile
Andreas Schwab b3ed821981 1999-07-19 Andreas Schwab <schwab@suse.de>
* libio/Makefile (routines): Add fwprintf.

	PowerPC has own version of w_sqrt.c and w_sqrtf.c.
	* math/w_sqrt.c: Moved to ...
	* sysdeps/generic/w_sqrt.c: ... here.
	* math/w_sqrtf.c: Moved to ...
	* sysdeps/generic/w_sqrtf.c: ... here.

	* Make-dist (generic-dirs): New variable.
	(try-sysdeps, +sysdep-names): Use it.
	* extra-lib.mk (all-$(lib)-routines): New variable.  Use it
	instead of $(lib)-routines.
	* elf/Makefile (distribute): Add dl-cache.h.
	* db2/Makefile (distribute): Add all new files.
	* iconvdata/Makefile (distribute): Don't distribute CVS
	directory.
	* math/Makefile (distribute): Remove machine/endian.h, add
	math_ldbl.h.
	* stdio-common/Makefile (distribute): Add _itowa.h.
	* sysdeps/generic/Dist: Remove make_siglist.c, add siglist.h.
	* sysdeps/gnu/Dist: Add eval.c
	* sysdeps/gnu/Makefile (libdl-sysdep_routines) [$(subdir) =
	dlfcn]: Add to this instead of libdl-routines.
	* sysdeps/ieee754/ldbl-128/Dist: New file.
	* sysdeps/mach/hurd/Dist: Add siglist.h
	* sysdeps/unix/sysv/linux/Dist: Add kernel-features.h.
