-# SYNOPSIS
-#
-#   AX_CC_MAXOPT
-#
-# DESCRIPTION
-#
-#   Try to turn on "good" C optimization flags for various compilers and
-#   architectures, for some definition of "good". (In our case, good for
-#   FFTW and hopefully for other scientific codes. Modify as needed.)
-#
-#   The user can override the flags by setting the CFLAGS environment
-#   variable. The user can also specify --enable-portable-binary in order to
-#   disable any optimization flags that might result in a binary that only
-#   runs on the host architecture.
-#
-#   Note also that the flags assume that ANSI C aliasing rules are followed
-#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
-#   computations can be re-ordered as needed.
-#
-#   Requires macros: AX_CHECK_COMPILE_FLAG, AX_COMPILER_VENDOR,
-#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.
