Tokenize a name, this is really pain, since a name can be a
filename or a symbol name. filenames have slashes and stuff whist
in an expression those things are seperate tokens. We hack this by
setting lang_in_expression when we are expecting a symbol, so that
setting ldlang_in_script when we are expecting a symbol, so that
[/+-] get taken to be seperate tokens. An extra gotcha is
expressions after defsyms, we only allow +s and -s in a defsym
expression, so -defsym foo=bar+9 /file.o is parsed ok.
The more I think about this the more I hate it. I've got a problem
now with the = sign, what should I do ? imagine:
__start=.;
You'd think that was pretty unambiguous wouldn't you. Well it's
not since __start=. is (at the moment) a perfectly valid
filename. And in some cases we don't know what's going on. I'm
going to have to hack this. If we see a '/' before the = sign then
we say we've got an = in a filename, otherwise it's an operator.
(later)
That's it, I've had enough. From now on, an =s on a command line
will be taken to be part of a file name unless its in a defsym,
and an = in a file will be taken to be an operator.
