Hi all,

I work with EPICS R3.13.1, vxWorks 5.3.1.
I started to work with Power PC board (mv2306). When I tried to build 
EPICS base I got following compilation error in base/rsrv:

gmake -C O.mv2306 -f ../Makefile.Vx T_A=mv2306 BUILD_TYPE=Vx install
gmake[1]: Entering directory `/import/epixF/solaris2/mks/slava/EpicsR3.13.1/bas

gmake: *** [install.mv2306] Error 2

the code line is:
                        logMsgArgs[i] = va_arg(args, int);

I didn't have such error when I built EPICS for mv162.
In tech-talk archives I've found the report of Nobory Yamamoto , where
were listed all remarked problems for Power PC EPICS (Beta12). Along with
other problems it was  mentioned there:

In R3.13.1 errPrintfVX.c module doesn't exist, it was completely rewritten
by M.Kraimer. But in rsrv/camessage.c module still exist codes dealing
with va_list and cause compilation error for PPC architecture.
