+# SYNOPSIS
+#
+# AX_GCC_BUILTIN(BUILTIN)
+#
+# DESCRIPTION
+#
+# This macro checks if the compiler supports one of GCC's built-in
+# functions; many other compilers also provide those same built-ins.
+#
+# The BUILTIN parameter is the name of the built-in function.
+#
+# If BUILTIN is supported define HAVE_<BUILTIN>. Keep in mind that since
+# builtins usually start with two underscores they will be copied over
+# into the HAVE_<BUILTIN> definition (e.g. HAVE___BUILTIN_EXPECT for
+# __builtin_expect()).
+#
+# The macro caches its result in the ax_cv_have_<BUILTIN> variable (e.g.
+# ax_cv_have___builtin_expect).
+#
+# The macro currently supports the following built-in functions:
+#
+# __builtin_assume_aligned
+# __builtin_bswap16
+# __builtin_bswap32
+# __builtin_bswap64
+# __builtin_choose_expr
+# __builtin___clear_cache
+# __builtin_clrsb
+# __builtin_clrsbl
+# __builtin_clrsbll
+# __builtin_clz
+# __builtin_clzl
