Fix variable declaration parsing

The following:
	int int_v = 4;
And:
	int v_int = 4;

Would confuse the compiler aka thinking it's a token and not an variable
declaration, since it expects the first N characters of the line will be
a variable name for a variable declaration, e.g.:
	int (N would be 3)
so, if we try something like:
	int_i = 4;
would fail and it would think that it's a variable declaration, and will
assume that the variable name is '_' while i is an operator or so.
