>Description:
I'm not able to build Boehm GC on NetBSD/sparc due to a mistake in source code. 
GC_push_regs is defined in C source (mach_dep.c) and in assembler 
(sparc_netbsd_mach_dep.s).
>How-To-Repeat:
Build Boehm GC (boehm-gc-7.1nb2) from pkgsrc on sparc and wait for crash ;-)
>Fix:
Please apply this patch.
