alpha-linux-gnulibc1 patch

alpha-linux-gnulibc1 patch

[Richard Henderson]

Linux/Alpha also has need for a "glibc1" option.  The difference
being that it actually was glibc 1.9x, rather than something HJ
and co. cooked up.  ;-)

	* config/alpha/elf.h (LINK_SPEC): ld.so changed between glibc 1.99
	and 2.0.0, so recognize USE_GNULIBC_1.
	* config.guess: Recognize alpha-linux-gnulibc1.
	* configure.in (alpha-*-linux-gnulibc1): New target.
	(alpha-*-linux-gnu*): Don't build crtbegin/end; crtstuff cannot
	handle some of the Alpha-specific details.  Correct versions are
	distributed with glibc.

Huh?

% gzcat *.gz | tar vtf -
drwxrws--- law/cygnus        0 Aug 15 15:42 1997 ./egcs-ss-970814/
-rw-rw---- law/cygnus   176520 Aug 15 11:55 1997 ./egcs-ss-970814/ChangeLog.10

Did you make a directory called egcs-ss-970814, then cd into it,
then extract the snapshot?
