glibc/sysdeps/libm-ieee754/w_jnf.c
Ulrich Drepper 9a8fcca0b3 Update.
* sysdeps/unix/sysv/linux/kernel-features.h: Define
	__ASSUME_SIOCGIFNAME for kernel >= 2.1.50.
	* sysdeps/unix/sysv/linux/if_index.c: Correct typo (SIOGIFNAME ->
	SIOCGIFNAME) and use __ASSUME_SIOCGIFNAME.

	* sysdeps/libm-ieee754/w_j0.c: Remove __ from symbol definitions.
	* sysdeps/libm-ieee754/w_j0f.c: Likewise.
	* sysdeps/libm-ieee754/w_j0l.c: Likewise.
	* sysdeps/libm-ieee754/w_j1.c: Likewise.
	* sysdeps/libm-ieee754/w_j1f.c: Likewise.
	* sysdeps/libm-ieee754/w_j1l.c: Likewise.
	* sysdeps/libm-ieee754/w_jn.c: Likewise.
	* sysdeps/libm-ieee754/w_jnf.c: Likewise.
	* sysdeps/libm-ieee754/w_jnl.c: Likewise.

	* stdio-common.c: Correct typos.

	* math/libm-test.c (jn_test): Adjust delta.
	(y1_test): Likewise.
	(yn_test): Likewise.

	* elf/do-lookup.h: It should never happen that if we expect a versioned
	symbol from a file the file has no version table.  This should have
	been checked in dl-version.c.
	* elf/dl-lookup.c: Include assert.h.
