I have been trying to take the compat/svr4 code from the current tree and put it in the 1.1 tree.
Here is what I have done and what problems I am having.
svr4_stat.c
 In function bsd_to_svr4_stat(~)
	 removed:
 	 st4->st_atim = st->st_atimespec.tv_sec;
 st4->st_mtim = st->st_mtimespec.tv_sec;
 st4->st_ctim = st->st_ctimespec.tv_sec;
 	 replaced with:
 st4->st_atim = st->st_atimespec.ts_sec;
 st4->st_mtim = st->st_mtimespec.ts_sec;
 st4->st_ctim = st->st_ctimespec.ts_sec;
svr4_signal.c
 in function svr4_to_bsd_sigaltstack(~)
 removed:
 bss->ss_base = sss->ss_sp;
 replaced with:
	 bss->ss_sp = sss->ss_sp;
 in function bsd_to_svr4_sigaltstack(~)
 removed:
 sss->ss_sp = bss->ss_sp;
 replaced with:
 sss->ss_sp = bss->ss_base;
svr4_net.c
 in function svr4_netopen(~)
 <omited code>
 struct socket *so;
 <omited code>
 so->so_internal = st;
 Same issue in function svr4_netclose(~)
 I checked sys/socketvar.h and there is no member
 "so_internal" the closest member (I can figure out) is
 so_state. Since so_state seems to be a short where so_internal seems to be an int, replacing one with another,
 via casting, doesn't seem to be the answer.
So do I need some new include files in sys? Seems easier than constantly patching.
I must say, I'm learning a lot about svr4 and NetBSD internals!
