I do believe you, but even so, I have never before programmed with a toolset
where I've had to use a modified name between asm and high-level code.  I
know that compilers commit all manner of hideous attrocities on identifier
names (esp. for linking), but there are quite a few that have managed to
prevent the mangling from having any visibility from the code's perspective.
(Or at least, they've hidden it from me. :=]  )

Come to think of it, cc65 is the first compiler I've used that actually
assembles the intermediate code generated by the compiler as a distinct
step (although many could be forced to output an assembly file as well).

Note: the first compiler I used was Borland Pascal for DOS, back in 1988.
And I had never used unix or linux for anything but checking mail with Pine,
until 2 years ago.  So (whether or not you cared..) that's where I come from.
