+   The basic API is described in the README file.
+
+   The raw API is designed to bypass some of the argument packing
+   and unpacking on architectures for which it can be avoided.
+
+   The closure API allows interpreted functions to be packaged up
+   inside a C function pointer, so that they can be called as C functions,
+   with no understanding on the client side that they are interpreted.
+   It can also be used in other cases in which it is necessary to package
+   up a user specified parameter and a function pointer as a single
+   function pointer.
+
+   The closure API must be implemented in order to get its functionality,
+   e.g. for use by gij.  Routines are provided to emulate the raw API
+   if the underlying platform doesn't allow faster implementation.
+
+   More details on the raw and cloure API can be found in:
+
+   http://gcc.gnu.org/ml/java/1999-q3/msg00138.html
+
+   and

+
+   The first four argument words on the stack are reserved for use by
+   the callee.  Instead, the general and floating registers replace
+   the first four argument slots.  Non FP arguments are passed solely
+   in the general registers.  FP arguments are passed in both general
+   and floating registers when using libffi.
+
+   Non-FP 32-bit args are passed in gr26, gr25, gr24 and gr23.
+   Non-FP 64-bit args are passed in register pairs, starting
+   on an odd numbered register (i.e. r25+r26 and r23+r24).
+   FP 32-bit arguments are passed in fr4L, fr5L, fr6L and fr7L.
+   FP 64-bit arguments are passed in fr5 and fr7.
+
+   The registers are allocated in the same manner as stack slots.
+   This allows the callee to save its arguments on the stack if
+   necessary:
+
+   arg word 3 -> gr23 or fr7L
+   arg word 2 -> gr24 or fr6L or fr7R
+   arg word 1 -> gr25 or fr5L
+   arg word 0 -> gr26 or fr4L or fr5R
+
+   Note that fr4R and fr6R are never used for arguments (i.e.,
+   doubles are not passed in fr4 or fr6).
+
+   The rest of the arguments are passed on the stack starting at SP-52,
+   but 64-bit arguments need to be aligned to an 8-byte boundary
+
+   This means we can have holes either in the register allocation,
+   or in the stack.  */

+# ===========================================================================
+#
+# 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_COMPILER_FLAGS, AX_COMPILER_VENDOR,
+#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

+   The basic API is described in the README file.
+
+   The raw API is designed to bypass some of the argument packing
+   and unpacking on architectures for which it can be avoided.
+
+   The closure API allows interpreted functions to be packaged up
+   inside a C function pointer, so that they can be called as C functions,
+   with no understanding on the client side that they are interpreted.
+   It can also be used in other cases in which it is necessary to package
+   up a user specified parameter and a function pointer as a single
+   function pointer.
+
+   The closure API must be implemented in order to get its functionality,
+   e.g. for use by gij.  Routines are provided to emulate the raw API
+   if the underlying platform doesn't allow faster implementation.
+
+   More details on the raw and cloure API can be found in:
+
+   http://gcc.gnu.org/ml/java/1999-q3/msg00138.html
+
+   and
