* Makerules ($(+sysdir_pfx)sysd-rules): Emit pattern rules to install

	into $(inst_includedir)/%.h from sysdirs.
	[headers]: Change static pattern rule for installing
	$(headers) to do only those not matching %.h.
	($(inst_includedir)/%.h: $(objpfx)%.h): Add this pattern rule instead.
	($(inst_includedir)/%.h: %.h): Likewise.
	($(inst_includedir)/%.h: $(..)include/%.h): Likewise.

	* Makefile ($(inst_includedir)/gnu/stubs.h):
	Add $(make-target-directory).

	* stdlib/Makefile (headers): Restore headers removed in last change.

2006-01-16  Jakub Jelinek  <jakub@redhat.com>

	* math/e_exp2l.c: Don't include stdio.h, errno.h, stub-tag.h, include
	math_private.h.
	(__ieee754_exp2l): Compute for now as expl (M_LN2l * x)
	instead of failing.
	(exp2l): Remove stub_warning.

2006-01-15  Jakub Jelinek  <jakub@redhat.com>

	* io/tst-faccessat.c (do_test): Don't fail if geteuid () == 0.
