Description
After updating bc to add a build dep against texinfo - needed for Ventura - builds for 10.6 are failing with a link error:
ld: duplicate symbol _edit in bc.o and main.o for architecture i386
Presumably texinfo isn't the culprit, since there isn't any linkage to it.
Could this be due to libedit, or...?

Replying to mascguy:
Not surprisingly, installing either without
+libedit- or using+readline- works fine. It's only the former that's now problematic.
Took a few minutes to look at upstream's configure script, etc - along with perusing the various sources and headers (both for bc, as well as libedit) - and it's not immediately obvious where public symbol _edit is coming from. But it's definitely an issue, as it exists in every bc object file.
So for now, let's fallback to +readline for 10.6 and earlier.

The edit variable is defined (not declared) in global.h, so every file that includes it will have its own definition. The definition should probably be moved to global.c and extern declarations put in global.h.

Replying to jmroot:
The
editvariable is defined (not declared) inglobal.h, so every file that includes it will have its own definition. The definition should probably be moved toglobal.cand extern declarations put inglobal.h.
While that makes sense, why does linking only fail on 10.6?

Different compiler, so possibly different defaults for common linkage.
