Once beta4 is ready I will definitely rebuild.

Well I'd say, this short before your expected release date, I wouldn't 
want to shake things up by adding another special Makefile.port with
the possible iterations to get it right. And although I would like it
to be otherwise, Siemens RM system have only a great market share in
Germany. I think, if Pyramid Nile users and, I think NEC has/had a MIPS
based SVR4, would speak up, then you should add a special MIPS based
Makefile.port

As I say, my system is pretty old (still R3000) and ths os is just as
old. And indeed the missing prototype in sys/time.h is the
cause. Later OS version have it defined. Therefore I really see no
need for changes here.

Well, this problem is originally caused by the need to link against
/usr/ucblib/libucb.a. Without libucb.a, I'm getting three undefined
symbols

 strncasecmp                         commands/SUBSYS.o
 alloca                              bootstrap/SUBSYS.o
 strcasecmp                          commands/SUBSYS.o

alloca is ok (GCC users have it build in). But strncasecmp and
strcasecmp are defined in the same archive member in
libucb.a. Therefore I get multiple defines if I link with strcasecmp.o 
from pgsql.

Come to think of it, shouldn't configure check also for strncasecmp if 
it checks for strcasecmp? But apparently, since no one complains, it
appears, that all other platforms do have strncasecmp and shouldn't
also need strcasecmp.

I general, I would say, leave the configure process as it is, once
beta4 is available. I'm quite happy as it stand, with all the
shortcommings of my dated hard- and software.
