It does not help modern compilers, and some may take some hit from it.

1.40, and it is the generally expected behaviour for NFS mounts.
Document the current defaults near the start of the man page and

to give up after one attempt unless a background mount is requested.
Background mounts would retry 10000 times (at least 7 days) before
giving up.
For some situations such as diskless terminals, an NFS filesystem
may be critical to the boot process, so neither the "try once" nor
background mounts are appropiate. To cater for this situation,
unbreak the -R (retry count) parameter so that it also works in
the non-background case. Interpret a zero retry count as "retry
forever".
The defaults are now "try once" for non-background mounts and "retry
forever" for background mounts; both can be overridden via -R.
Add a description of this behaviour to the manpage.
ensure that we never proceed with the mount() syscall if the server
is replying from the wrong source address. Previously the userland
RPC call to the remote nfsd would succeed, but the kernel uses
connect() so it would not see the replies, resulting in a hung
mount.
NQNFS code is ancient, bug-ridden, and should probably be removed).
The wording here was very confusing; it was easy to get the impression
that NQNFS is an extension to NFSv3 when in fact it just uses some
NFSv3-like extensions on top of NFSv2. As witnessed by the mailing
lists and PRs, some people were reading the description and deciding
that NQNFS was what they wanted to use.

number of issues:
- Fix background mounts; these were broken in revision 1.40.
- Don't give up before trying all addresses returned by getaddrinfo().
- Use protocol-independent routines where possible.
- Improve error reporting for RPC errors.
- In non-background mode, give up after trying all protocols once.
- Use daemon(3) instead of rolling our own version.
- Never go ahead with the mount() syscall until we have received
a reply from the remote nfsd; this is especially important with
non-interruptible mounts, as otherwise a mistyped command might
require a reboot to correct.

Bring in required TLI library routines to support this.
Since we don't support TLI we've essentially copied what NetBSD
has done, adding a thin layer to emulate direct the TLI calls
into BSD socket calls.
This is mostly from Sun's tirpc release that was made in 1994,
however some fixes were backported from the 1999 release (supposedly
only made available after this porting effort was underway).
The submitter has agreed to continue on and bring us up to the
1999 release.
Several key features are introduced with this update:
Client calls are thread safe. (1999 code has server side thread
safe)
Updated, a more modern interface.
Many userland updates were done to bring the code up to par with
the recent RPC API.
There is an update to the pthreads library, a function
pthread_main_np() was added to emulate a function of Sun's threads
library.
While we're at it, bring in NetBSD's lockd, it's been far too
long of a wait.
New rpcbind(8) replaces portmap(8) (supporting communication over
an authenticated Unix-domain socket, and by default only allowing
set and unset requests over that channel). It's much more secure
than the old portmapper.
Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
to support TI-RPC and to support IPV6.
Umount(8) is also fixed to unmount pathnames longer than 80 chars,
which are currently truncated by the Kernel statfs structure.

Made mount more userfriendly (bad slashes are now filtered out)

Fixed mount_xxx binarys to resolve with realpath(3)

Translate the deprecated nfs-syntax with '@' to ':' .
The ':' syntax has now precedence, but '@' still works.
Notify the user that the '@' syntax should not be used.
