From: Mike Frysinger Date: Sat, 1 May 2021 22:00:27 +0000 (-0400) Subject: gnulib: import getline X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c17253b97437c8dbc778cb0f16aef46693855bf0;p=binutils-gdb.git gnulib: import getline We use getline in sim today which breaks on older systems that are not compliant with the latest POSIX standard. For example, mingw64 for Windows omits getline so we fail to build there. --- diff --git a/gnulib/ChangeLog b/gnulib/ChangeLog index 810aa1e62da..8e14d308eb1 100644 --- a/gnulib/ChangeLog +++
