>Description:

	I just happened to switch to the window building xendtools411 at
	the right time to see the following warning scroll by:

net/fcels.c: In function 'fc_els_echo_rx_request':
net/fcels.c:1267:16: warning: implicit declaration of function 'suzeif' [-Wimplicit-function-declaration]
  size_t plen = suzeif(*echo) + len - sizeof ( struct fc_echo_frame_header );
                ^~~~~~

	I'm guessing this is a typo for "sizeof()" (a hand-shifted-left
	error), though I cannot be 100% sure since oddly this doesn't
	seem to have had any adverse affect on the build, which
	completes with a package that installs A-OK.

	I have not yet run the resulting package yet though.

	On the other hand this seems to have been in place since the
	original xentools411 as the line is introduced by a pkgsrc patch
	(patches/patch-.._ipxe_src_net_fcels.c), and it's been there
	since the inception of xentools411 on 2018-07-24.

	I'm guessing the patched file is compiled as part of one of the
	qemu firmware files, but why it didn't generate a link error
	that should have halted the build I have no clue.

>How-To-Repeat:

	capture stderr for a build of xentools411
