c++: beware of Visual C++ limitations
Contrary to what commit d8cc6b073e2802d871a16dc62418a7eb62ed2216 "c++:
shorten the assertions that check whether tokens are correct"
believed, MS Visual C++'s preprocessor limitation is not on the input
line length, but on the size of the line holding the full C++
statement.

* data/skeletons/variant.hh (_b4_symbol_constructor_define): Hide the
assertion from Visual C++.
