compile problem on a vax

Hello,

I have been trying to compile postgresql-7.0.3 on a uVax II running NetBSD
1.5, after some problems i am almost there, now i only get these errors
during the final compile:

>gcc -I../include -I../backend -O2 -pipe -Wall -Wmissing-prototypes -Wmissin
g-declarations -o postgres access/SUBSYS.o bootstrap/SUBSYS.o
>catalog/SUBSYS.o commands/SUBSYS.o executor/SUBSYS.o lib/SUBSYS.o
libpq/SUBSYS.o main/SUBSYS.o parser/SUBSYS.o nodes/SUBSYS.o
>optimizer/SUBSYS.o port/SUBSYS.o postmaster/SUBSYS.o regex/SUBSYS.o
rewrite/SUBSYS.o storage/SUBSYS.o tcop/SUBSYS.o >utils/SUBSYS.o
../utils/version.o -lcrypt -lcompat -lm -lutil -ltermcap -lcurses
>access/SUBSYS.o: Undefined symbol `r0' referenced
>storage/SUBSYS.o: Undefined symbol `r0' referenced
>collect2: ld returned 1 exit status
>gmake[1]: *** [postgres] Error 1
>gmake[1]: Leaving directory `/dinges/temp/postgresql-7.0.3/src/backend'
>gmake: *** [all] Error 2

I have change something in /src/include/storage/s_lock.h (because else i
would get another error, saying that slock_t was already defined in os.h):

Can anybody help me and explain to me how to fix this?

Are there people here that have any postgresql version running on the vax?
which version do you use and which OS for your vax

thank you,
