I know that {p,}gcc-2.95.2{,.1} are not officially supported.
Did you know that it's impossible to compile nfsv4 because of register allocation problems with long long since (long long) month ?
The following does not hurt, it's just a fix for a broken compiler:
--- linux/fs/lockd/xdr4.c.orig Fri Dec 29 01:35:32 2000 +++ linux/fs/lockd/xdr4.c Fri Dec 29 01:36:36 2000 @@ -156,7 +156,7 @@ nlm4_encode_lock(u32 *p, struct nlm_lock *lock) { struct file_lock *fl = &lock->fl; - __s64 start, len; + volatile __s64 start, len; if (!(p = xdr_encode_string(p, lock->caller)) || !(p = nlm4_encode_fh(p, &lock->fh))
Here is an example without this patch (pgcc-2.95.2.1 this time which is bug-compatible to gcc-2.95.2.1).
