Update.

1999-06-07  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* sysdeps/unix/sysv/linux/if_index.c: Use SIGIOCGIFINDEX and fix
	another SIOGIFNAME typo.

1999-06-07  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dl-lookup.c: Remove duplicated assert.h inclusion.

	* sysdeps/generic/printf_fphex.c (__printf_fphex): Optimize a little
	bit.

1999-06-05  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* sysdeps/generic/printf_fphex.c (__printf_fphex): Don't ignore
	the precision if the mantissa is zero.

1999-06-05  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* manual/lang.texi (Floating Point Parameters): GCC already
	supports long double for a long time.

1999-06-05  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* math/libm-test.c (j0_test, j1_test, jn_test, y0_test, y1_test,
	yn_test): Increase some epsilons.
