From e94b4f23277f7572aacbbeae50b8927e03be148a Mon Sep 17 00:00:00 2001 From: Petr Vorel Date: Thu, 15 Jul 2021 17:35:27 +0200 Subject: [PATCH 1/2] osdep: Introduce include/grub/osdep/major.h and use it ... to factor out fix for glibc 2.25 introduced in 7a5b301e3 (build: Use AC_HEADER_MAJOR to find device macros). Note: Once glibc 2.25 is old enough and this fix is not needed also AC_HEADER_MAJOR in configure.ac should be removed.
