This was introduced by a recent commit adding a testcase matching
an example in the manual. There doesn't seem to be a suitable
termplate in the standard library before C++11, so instead use
a dummy version of std::array defined in the testcase.
If it's not a recognised directive the scanner now emits MODULO and then
rescans what follows, and if the parser then gives a syntax error we
report it as an unknown directive. This means that `a%b` is now allowed
in an expression, and that things like `%std::vector<std::string>` now
give an error rather than being quietly ignored.
Fixes#300Fixes#368
Adding full support for these in expressions seems hard to do without
introducing conflicts into the parser grammar, but in fact all reported
cases have had parentheses around the comparison and we can support that
with a few restrictions on the left side of `<`.
Fixes#80 and #635. Also https://sourceforge.net/p/swig/bugs/1139/
