Hello Klaus,

I had a look into the SVN repo of the yasm port, here:
http://svnweb.freebsd.org/ports/head/devel/yasm/Makefile?view=log
the last version change dates from Feb 2012; so this does not look as a
yasm regresion for me.

And if you look into the output produced by the yasm' preproc,
http://www.unixarea.de/yasm.out
why yasm does know X86FXSTATE_size at line  733 in yasm.out:

X86FXSTATE_size EQU $ - X86FXSTATE

but not X86TSS16_size in line 765:

X86TSS16_size EQU $ - X86TSS16

i.e. from where it knows X86FXSTATE_size, but not X86TSS16_size?

Seems so.
