Problems compiling 6.4.2 for Alpha-Linux

I'm having the following problem while compiling Postgres 6.4.2 on a Dec

Alpha (Multia, an Alpha - 21066a) running Red Hat Alpha-Linux. I was
wondering if anyone out there has any clues as to why datetime.c is
bombing the compiler - and if so,
if there are any patches out there to remedy the problem.

Here's a clip of the make-----------

make[3]: Entering directory
`/usr/local/pg/postgresql-6.4.2/src/backend/utils/ad t' gcc
-I../../../include -I../../../backend -O2 -mieee -Wall
-Wmissing-prototypes -I../.. -c datetime.c -o datetime.o

Please send comments to whilenot1(at)excite(dot)com as I am not an avid group
reader.

Much appreciated!
