[Simh] OpenBSD (5.6) issues

[Cory Smelosky]

All,

Seem to be a few issues building latest GIT on OpenBSD.

csmelosky at maelona: ~/simh git reset --hard
HEAD is now at a0c7f99 scp: avoid redefining MAX
csmelosky at maelona: ~/simh nano makefile
csmelosky at maelona: ~/simh gmake
lib paths are: /usr/lib /usr/X11R6/lib /usr/local/lib
include paths are: /usr/include /usr/local/include
using libm: /usr/lib/libm.a
using libpthread: /usr/lib/libpthread.a /usr/include/pthread.h
using libpcreposix: /usr/local/lib/libpcreposix.a 
/usr/local/include/pcreposix.h
using libdl: /usr/include/dlfcn.h
using libSDL: /usr/local/lib/libSDL.a /usr/local/include/SDL/SDL.h
using libpcap: /usr/include/pcap.h
***
*** all  Simulators being built with:
*** - compiler optimizations and no debugging support. GCC Version: 4.2.1.
*** - dynamic networking support using OpenBSD provided libpcap 
components.
*** - Local LAN packet transports: PCAP TAP
*** - video capabilities provided by libSDL (Simple Directmedia Layer).

$ gcc -v
Reading specs from /usr/lib/gcc-lib/amd64-unknown-openbsd5.6/4.2.1/specs
Target: amd64-unknown-openbsd5.6
Configured with: OpenBSD/amd64 system compiler

gcc version 4.2.1 20070719

Issue reproducible with clang.
clang version 3.5 (trunk)

However, it links fine with a later GCC:
$ /usr/local/bin/egcc -v
Using built-in specs.
