Re: DEC OSF compile fails in buf_init.c

Hi all! I saw the following bug report in the mailinglist archive,
but haven't seen much feedback/bugfix. I'm having the similar
problem when I was trying to compile postgresql 6.5.2 on Digital Unix 4.0d.
Wonder if anyone has worked out a fix, and kindly post it?

Thanks very much,

Your name : Jarda Benkovsky

Category : install: compile
Severity : serious

Summary: syntax errors in spinlocks (s_lock.h)

System Configuration
--------------------
Operating System : Digital Unix 4.0e

PostgreSQL version : 6.4.2

Compiler used : gcc 2.8.1, DEC C V5.8-009

Hardware:
---------
Alpha 2100
uname -a: OSF1 shadow.pvt.net V4.0 1091 alpha

Versions of other tools:
------------------------
gnu make

--------------------------------------------------------------------------

Problem Description:
--------------------
On Digital Unix alphas, msemaphores are defined as a struct of two ints.
Neither gcc, nor native do not like constructs like *(lock) = 0;

Native cc:

/usr/bin/cc -I../../../include -I../../../backend -DNOFIXADE -I../.. -c buf_init.c -o buf_init.o
cc: Error: buf_init.c, line 234: In this statement, "0" is of type "int", and cannot be converted to "struct declared without a tag". (noconvert)
S_INIT_LOCK(&(buf->io_in_progress_lock));
------------------------^

GCC:
../../../include/storage/s_lock.h: In function `tas':
In file included from buf_init.c:29:
../../../include/storage/s_lock.h:102: aggregate value used where an integer was expected
buf_init.c: In function `InitBufferPool':
buf_init.c:234: incompatible types in assignment

Especially the case of native CC is interesting, as there
should not be such case and I was not able to reproduce
it in controlled environment - but maybe I did some mistake
during the test.

Test Case:
----------
./configure; make
