--- Comment #13 from Sandra Loosemore <sandra at codesourcery dot com> 2012-01-27 20:14:22 UTC --- Sigh. I think it would be OK to make -frepo imply --no-demangle, and document that this is the case. If my previous patch is reverted, that'll still leave -frepo broken on Windows hosts (because the logic in collect2 to disable demangling in ld was broken on Windows) in addition to re-breaking mapfile demangling on both Windows and Posix in the "normal" case where you aren't using -frepo. WDYT?
