### identifiers and symbol names
### Identifiers and Symbol names
* any symbols that are exported from source files and/or appear in header files should not be in the "_symbol" form in C, or "__symbol" form in assembly. This way we evade the problem that "_symbol" may or may not be reserved by that standard.
The C Standard defines certain identifiers and symbol names, which we can not use
in our code. Since it is not always obvious which parts of the library code will
actually end up in a linked program, the following applies to ALL of the library.
Any non standard identifier/symbol/function that is exported from source files,
or appears in header files:
* must not be in the "_symbol" form in C, or "__symbol" form in assembly.
* must start with (at least) two (C Code) or three (assembly code) underscores, unless the symbol appears in a non standard header file.
This is likely more than the standard dictates us to do - but it is certainly
standard compliant - and easy to remember.
Also see the discussion in https://github.com/cc65/cc65/issues/1796

### name clashes in the library
see "Identifiers and Symbol names" above - not all identifiers have been checked
and renamed yet. The following is a list of those that still might need to be
fixed:
