Very true. And by definition, there should really only be one ABI...
if it comes up as a bug again somewhere else, we can look into this.

Well, unless your mailer ate a "+" at the beginning of "return 1;", it
wasn't right in the mail. That line is moving over. I'm sure you'll
have it right when you commit it :)

Thanks. We may not have consistent grammar or spelling in our messages
right now, but I'm still all over trying.

"ABIs" looks like what I remember, too, so let's use that.

Shall we agree to mimic "set language", then?

[For anyone following along:

(gdb) set language
The currently understood settings are:

local or auto Automatic setting based on source file
c Use the C language
c++ Use the C++ language
asm Use the Asm language
chill Use the Chill language
fortran Use the Fortran language
java Use the Java language
modula-2 Use the Modula-2 language
pascal Use the Pascal language
scheme Use the Scheme language
(gdb) show language
The current source language is "auto; currently c".
