-# 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_ctz

-#    __builtin_ctzll
-#    __builtin_expect
-#    __builtin_ffs
-#    __builtin_ffsl
-#    __builtin_ffsll
-#    __builtin_fpclassify
-#    __builtin_huge_val
-#    __builtin_huge_valf

-#    __builtin_infd64
-#    __builtin_inff
-#    __builtin_infl
-#    __builtin_isinf_sign
-#    __builtin_nan
-#    __builtin_nand128
-#    __builtin_nand32
-#    __builtin_nand64
-#    __builtin_nanf
-#    __builtin_nanl
-#    __builtin_nans

-#    __builtin_powil
-#    __builtin_prefetch
-#    __builtin_trap
-#    __builtin_types_compatible_p
-#    __builtin_unreachable
-#
-#   Unsuppored built-ins will be tested with an empty parameter set and the
-#   result of the check might be wrong or meaningless so use with care.
