I'm busy porting postgres 4.2 to NetBSD 1.0 and I came across  the
following error:

cc -O -DPORTNAME_netbsd -DPOSTPORT='"4321"' -DDEADLOCK_TIMEOUT=60 -DPOSTGRESDIR='"/usr/local/postgres"'  -DDATADIR='"/usr/local/postgres/data"'  -DBINDIR='"/usr/local/postgres/bin"'  -I/usr/postgres/src/backend/. -I/usr/postgres/src/backend/obj  -I/usr/postgres/src/backend/tmp  -I/usr/postgres/src/backend/port/netbsd  -c /usr/postgres/src/backend/storage/ipc/s_lock.c
/usr/postgres/src/backend/storage/ipc/s_lock.c: In function `tas':
/usr/postgres/src/backend/storage/ipc/s_lock.c:283: `m' undeclared (first use this function)
/usr/postgres/src/backend/storage/ipc/s_lock.c:283: (Each undeclared identifier is reported only once
/usr/postgres/src/backend/storage/ipc/s_lock.c:283: for each function it appears in.)
*** Error code 1

The code segment that is giving me the problem looks like this

#if defined(__i386__) && defined(__GNUC__)
 
tas(lock)
    slock_t *lock;
{
    slock_t res;
    __asm__("xchgb %0,%1":"=q" (res),"=m" (*m):"0" (0x1));
    return(res);
}
 
line 283 is the __asm__ line. My questin is where is "m" supposed to
be defined and why does this compile for other OS's (i.e. linux freebsd),
or does it. I'm not an assembly guru so any help you can give me is
appreciated.

Thanks,
