Seems like a reasonable idea.

I'm not sure what the "const" here is good for, and I can think of
some compilers that are likely to get confused too:

Also, are you sure that code to identify the placeholders is robust?
Should you be defending against '%' in the syntax string?
Will the NLS infrastructure remember to build sql_help.c before
looking for strings?
