Re: [Nmh-workers] nmh internals: argument processing

[Paul Fox]

does this solution lead to symbols that can't be found with
simple search tools?  a quick skim made me think it doesn't, but
wanted to check.  i.e., will i find a reference to, say, MARK_FOO
in the code that i can't grep for, because it was constructed with
    name ## _FOO
or something like that?

if not, i'm all for it.  otherwise i think the obfuscation isn't worth it.

(the linux kernel is full of variable names constructed like that,
making it very difficult to find important declarations.)
