Hi,
this is to mitigate a race condition in expect 5.45-7 (which will be fixed in 5.45-8) see this thread for details: https://gcc.gnu.org/ml/gcc/2017-07/msg00081.html By increasing the match buffer size from 2000 to 10000 bytes we can avoid the fall-out due to the bug in expect, while we have to wait for the next stable debian version. Bootstrapped and reg-tested on x86_64-pc-linux-gnu. Is it OK for trunk? Thanks Bernd.
