While working on the parser code, I noticed that yyerror is exported
from each parser. It is used by this code in parse.c:
TRY
{
if (lang->la_parser (&ps))
lang->la_error (NULL);
}
However, it seems to me that la_error will never be called here,
because in every case, la_parser throws an exception on error -- each
implementation of yyerror just calls error.
So, this patch removes la_error and makes all the yyerror functions
static. This is handy primarily because it makes it simpler to make
the expression parsers pure.
Tested by the buildbot.
