Hi,
there are two problems in the following definitions (line 90--99).
1. Extra "s" on \ifparameter
2. \anch_table_check_state doesn't work anymore because it tries to
change the value of \dosingleempty which was used to create the
optional argument.

How about this:
\permanent\protected\def\tbXC
{\anch_table_checked\anch_tables_indeed_XC }
\permanent\protected\def\tbGSC{\anch_table_checked\anch_tables_indeed_GSC}
\permanent\protected\def\tbGFC{\anch_table_checked\anch_tables_indeed_GFC}
\permanent\protected\def\tbGTC{\anch_table_checked\anch_tables_indeed_GTC}
\tolerant\def\anch_table_checked#1[#2]%
{\iftrialtypesetting
\global\settrue\tablehaspositions
\expandafter\NC
\orelse\ifparameter#2\or
\expandafter#1%
\else
\expandafter\NC
\fi}
The optional argument is now gone and never passed further down, more
something like this (not sure about \tripleexpandafter)
\tolerant\def\anch_table_checked#1[#2]%
{\iftrialtypesetting
\global\settrue\tablehaspositions
\tripleexpandafter\NC\expandafter\gobbleoneoptional
\orelse\ifparameter#2\or
\expandafter#1%
\else
\tripleexpandafter\NC\expandafter\gobbleoneoptional
\fi[#1]}
We're nearly there ... pass [#2] istead of [#1] ...
