Compiler warnings

[dschwen]

We're about to use this library in a big software project that has strict guidelines about compiler warnings. The parser library emits a bunch of unused parameter warnings. We could silence -Wunused-parameter for the parser includes, but you might be interested in cleaning those up.

These comparison is always false due to limited range of data type warnings are a bit concerning. Looks like curr_c is a signed char, which cannot represent 0xe0 etc.
