+Subject: [PATCH] m4: Backport ax_prog_cc_for_build.m4 macros
+
+autoconf-2.73 has logic to use C23 which spills into CC_FOR_BUILD [1]
+Bring back the upstream fix from autoconf-archives, this should not
+be needed when sudo is updated to next version as it might have
+regenerated its autotools files and it would have it.
+
+[1] https://savannah.gnu.org/support/index.php?111401
+
+Upstream-Status: Inappropriate [Already in autoconf-archive ]

++dnl their values in alternative names, and restore the values later.
++dnl
++dnl _AC_COMPILER_EXEEXT and _AC_COMPILER_OBJEXT internally call
++dnl AC_SUBST which prevents the renaming of EXEEXT and OBJEXT
++dnl variables. It's not a good idea to rename ac_cv_exeext and
++dnl ac_cv_objext either as they're related.
++dnl Renaming ac_exeext and ac_objext is safe though.

This does not build on hosts with gcc <= 13 which does not have std=gnu23 dialect option e.g. ubuntu 24.04, especially with clang which does not default to gnu23 yet like gcc-15, so autoconf 2.73 decided to enforce the standard with clang which then spills into CC_FOR_BUILD as well without this patch Signed-off-by: Khem Raj <khem.raj@oss.qualcomm.com> --- ...kport-ax_prog_cc_for_build.m4-macros.patch | 229 ++++++++++++++++++ meta/recipes-devtools/strace/strace_6.19.bb | 1 + 2 files changed, 230 insertions(+) create mode 100644 meta/recipes-devtools/strace/strace/0001-m4-Backport-ax_prog_cc_for_build.m4-macros.patch
