Windows XP : error...does not have native spinlock support on this platform

Greetings,

 

Magnus...thanks for the token (dynamic buffer) patch...

 

I encounter the following error when attempting to "make" the November 15 snapshot using minGW/MSYS on Windows XP SP1 w/o admin privileges (the message suggests posting to the "bugs" list but based on the list descriptions...I am posting to the "ports" list):

 

port/win32" -DBUILDING_DLL  -c -o xlog.o xlog.c
In file included from ../../../../src/include/storage/spin.h:50,
                 from xlog.c:35:
../../../../src/include/storage/s_lock.h:543:2: #error PostgreSQL does not have native spinlock support on this platform. To continue the compilation, rerun configure using --disable-spinlocks. However, performance will be poor. Please report this to pgsql-bugs@postgresql.org.

Any help is appreciated,
