From 9c9d63b15ad548f65f8bfd41cb7a4ef9af5ccb28 Mon Sep 17 00:00:00 2001 From: "Paul E. Murphy" Date: Fri, 22 Jan 2021 13:55:45 -0600 Subject: gnulib: update to 776af40e0 This fixes PR27184, a failure to compile gdb due to cdefs.h being out of sync with glibc on ppc64le targets which are compiled with -mabi=ieeelongdouble and glibc 2.32. Likewise, update usage of _GL_ATTRIBUTE_FORMAT_PRINTF to _GL_ATTRIBUTE_FORMAT_PRINTF_STANDARD. Likewise, disable newly added rpl_free gnulib api in gdbserver support libraries. Likewise, undefine read/write macros before redefining them on mingw targets. Likewise, wrap C++ usage of free with GNULIB_NAMESPACE namespace as needed.
