	``configure`` now uses a standardized format to forward state, compiler flags, and linker flags to ``Makefile``, ``setup.py``, and ``Modules/Setup``. ``makesetup`` use the new variables by default if a module line does not contain any compiler or linker flags. ``setup.py`` has a new function ``addext()``. For a module ``egg``, configure adds: * ``MODULE_EGG`` with value yes, missing, disabled, or n/a * ``MODULE_EGG_CFLAGS`` * ``MODULE_EGG_LDFLAGS`` ``Makefile.pre.in`` may also provide ``MODULE_EGG_DEPS`` that lists dependencies such as header files and static libs.

						|
#   AX_C_FLOAT_WORDS_BIGENDIAN([ACTION-IF-TRUE], [ACTION-IF-FALSE], [ACTION-IF-UNKNOWN])
 | 
						|
#
 | 
						|
# DESCRIPTION
 | 
						|
#
 | 
						|
#   Checks the ordering of words within a multi-word float. This check is
 | 
						|
#   necessary because on some systems (e.g. certain ARM systems), the float
 | 
						|
#   word ordering can be different from the byte ordering. In a multi-word
 | 
						|
#   float context, "big-endian" implies that the word containing the sign
 | 
						|
#   bit is found in the memory location with the lowest address. This
 | 
						|
#   implementation was inspired by the AC_C_BIGENDIAN macro in autoconf.
 | 
						|
#
 | 
						|
#   The endianness is detected by first compiling C code that contains a
 | 
						|
#   special double float value, then grepping the resulting object file for
 | 
						|
#   certain strings of ASCII values. The double is specially crafted to have
 | 
						|
#   a binary representation that corresponds with a simple string. In this
 | 
						|
#   implementation, the string "noonsees" was selected because the
 | 
						|
#   individual word values ("noon" and "sees") are palindromes, thus making
 | 
						|
#   this test byte-order agnostic. If grep finds the string "noonsees" in
 | 
						|
#   the object file, the target platform stores float words in big-endian
 | 
						|
#   order. If grep finds "seesnoon", float words are in little-endian order.
 | 
						|
#   If neither value is found, the user is instructed to specify the
 | 
						|
#   ordering.

 | 
						|
#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
 | 
						|
#
 | 
						|
# DESCRIPTION
 | 
						|
#
 | 
						|
#   Check whether the given FLAG works with the current language's compiler
 | 
						|
#   or gives an error.  (Warnings, however, are ignored)
 | 
						|
#
 | 
						|
#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
 | 
						|
#   success/failure.
 | 
						|
#
 | 
						|
#   If EXTRA-FLAGS is defined, it is added to the current language's default
 | 
						|
#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
 | 
						|
#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
 | 
						|
#   force the compiler to issue an error when a bad flag is given.
 | 
						|
#
 | 
						|
#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
 | 
						|
#
 | 
						|
#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
 | 
						|
#   macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

# DESCRIPTION
 | 
						|
#
 | 
						|
#   Look for OpenSSL in a number of default spots, or in a user-selected
 | 
						|
#   spot (via --with-openssl).  Sets
 | 
						|
#
 | 
						|
#     OPENSSL_INCLUDES to the include directives required

						|
#     OPENSSL_LIBS to the -l directives required
 | 
						|
#     OPENSSL_LDFLAGS to the -L or -R flags required
 | 
						|
#
 | 
						|
#   and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately
 | 
						|
#
 | 
						|
#   This macro sets OPENSSL_INCLUDES such that source files should use the
 | 
						|
#   openssl/ directory in include directives:
 | 
						|
#
 | 
						|
#     #include <openssl/hmac.h>
