Re: smoothing Xcode integration

[Uxio Prego]

On StackOverflow I've been given some directions on getting Xcode
to correctly use a cross platform Makefile, however haven't been
completely successful so far.

I can add a target wrapping the Makefile, but haven't passed the
environment variables to the `make` execution successfully yet,
for it to remove the _line_ preprocessor directives.

Also I haven't figured out yet how to configure that Make target as
a build step before the program target itself.

I probably don't really understand this question.

Can't you eventually achieve the same results via either the
"Cross-platform" > "External Build System" wizard or
(e.g.) the "macOS" > "Command Line Tool"?

Nice to know, however maybe the `sed` use is more convenient.
The default flow must be not to manipulate _line_ preprocessor
directives.

If I added `%no-lines`, would GDB debugging break?
I'd try once I have a Linux box at hand again...

So unless nothing breaks, injecting a `%no-lines` line in the Bison
doc, I see unnecessarily complicated compared to optionally run
a simple `sed` substitution on the generated parser.
