From: Simon Marchi Date: Fri, 29 Apr 2022 12:39:24 +0000 (-0400) Subject: gnulib: update to bd11400942d6 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b318629fe742b2d9595eee1a2c35e81149ba33b2;p=binutils-gdb.git gnulib: update to bd11400942d6 Update the gnulib import to fixes these issues: - GDB build with clang + glibc < 2.33. https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=d6a07b4dc21b3118727743142c678858df442853 https://lists.gnu.org/archive/html/bug-gnulib/2022-04/msg00072.html With glibc < 2.33, gnulib (since relatively recently) enables a replacement for free (see gnulib/import/m4/free.m4).
