System: NetBSD stand.degler.net 1.6W NetBSD 1.6W (STAND) #6: Sun Aug 3 00:21:07 EDT 2003 root@stand.degler.net:/vol1/NetBSD/kernels/STAND alpha
Architecture: alpha
Machine: alpha
>Description:

The reach over Makefile for libgcc3 only selects .c files and omits
assembly files.  Furthermore, the gcc distribution includes the
assembly files with an ".asm" extension, for which NetBSD provides no
implicit rules.  My fix includes a copy of the .asm file to a ".S" file,
which is then handled properly by the default make rules.

>How-To-Repeat:
	build netbsd -current on alpha and then try to build perl5.
	observe the symbols missing from libgcc.

>Fix:
This patch, while ugly, seems to work fine.
