+From: Adrian Ratiu <adrian.ratiu@collabora.com>
+Date: Mon, 30 Aug 2021 18:43:13 +0300
+Subject: [PATCH] configure.ac: rework gnu99 ext check to allow clang
+
+It is true that Clang does not support all gnu99 extensions [1],
+but not all of them are used in the codebase and over time there
+have been code cleanup efforts to improve Clang support.
+
+For example after commit 779c57ea ("readelf: Pull advance_pc()
+in file scope") there are no more nested function declarations
+and elfutils now builds fine with Clang.
+
+So in the interest of enabling Clang builds we remove the only
+remaining blocker: the configure checks for nested functions and
+variable length arrays which are also unused.
+
+Considering mixed decls and code is also part of c99 standard,
+the entire check becomes redundant and we can just replace
+AC_PROG_CC -> AC_PROG_CC_C99.
+

+Subject: [PATCH] readelf: Pull advance_pc() in file scope
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Make advance_pc() a static function so we can get rid of another nested
+function. Rename it to run_advance_pc() and use a local advance_pc()
+macro to pass all the local variables. This is similar to what the
+equivalent code in libdw/dwarf_getsrclines.c is doing.
