Problems compiling PostgreSQL 6.4 on Digital Unix 4.0d

I am having some trouble compiling version 6.4 on Digital Unix 4.0d.  The
first problem I ran into was a function prototyping error in snprintf.c.
Here is the SCCS diff of the fix that I had to do to make it compile:

------- snprintf.c -------
123a124,126
> #ifdef HAVE_LONG_INT_64
> static void fmtnum __P((long_long value, int base, int dosign, int ljust, int len, int zpad));
> #else
124a128
> #endif


However, now the compile fails with all of this:


gcc -I../../../include -I../../../backend   -DNOFIXADE  -Wall
  -Wmissing-prototypes -I../..   -c buf_init.c -o buf_init.o
  ../../../include/storage/s_lock.h: In function `tas':

And then:

Can someone suggest fixes for these errors?
