Summary: libcpp aclocal.m4 and configure incorrectly
regenerated
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
Running either 'autoreconf' or 'aclocal -I ../config' in libcpp/ generates
aclocal.m4 and configure scripts with slightly different contents from what is
currently in the repo:

Are these files incorrect in the repo?
I tried to remove ../config/override.m4 and run either 'autoreconf' or 'aclocal
-I ../config', then the result is the same as what is in the repo: override.m4
is not needed by libcpp, but still analyzed by aclocal, and it does have a
sligh effect when generating configure.
Is the fix to commit the above differences, or is there another recipe to
regenerate these files?
