- tolerate, so the alphabet this function creates is a little odd.
- Here are some sample mangled identifiers offered by HP:

- this is right, but I still strongly suspect that there's a
- misunderstanding here.
-
- If we decide it's better for c++filt to use HP's assembler syntax
- to scrape identifiers out of its input, here's the definition of
- the symbol name syntax from the HP assembler manual:
-
- Symbols are composed of uppercase and lowercase letters, decimal
- digits, dollar symbol, period (.), ampersand (&), pound sign(#) and
- underscore (_). A symbol can begin with a letter, digit underscore or
