++dnl are not useful to us. Pretty much everything depends just on gmp.h,

++dnl be rebuilt for changes to those files.
++dnl
++dnl "no-dependencies" also helps with the way we're setup to run

++dnl automake (eg 1.7.2) appends an AM_CONDITIONAL to AC_PROG_CXX, and then

++# Table of compilers, options, and mpn paths. This code has various related
++# purposes
++#
++# - better default CC/CFLAGS selections than autoconf otherwise gives
++# - default CC/CFLAGS selections for extra CPU types specific to GMP
++# - a few tests for known bad compilers
++# - choice of ABIs on suitable systems
++# - selection of corresponding mpn search path
++#
++# After GMP specific searches and tests, the standard autoconf AC_PROG_CC is
++# called. User selections of CC etc are respected.
++#
++# Care is taken not to use macros like AC_TRY_COMPILE during the GMP
++# pre-testing, since they of course depend on AC_PROG_CC, and also some of
++# them cache their results, which is not wanted.
++#
++# The ABI selection mechanism is unique to GMP. All that reaches autoconf
++# is a different selection of CC/CFLAGS according to the best ABI the system
++# supports, and/or what the user selects. Naturally the mpn assembler code
++# selected is very dependent on the ABI.
++#
++# The closest the standard tools come to a notion of ABI is something like
++# "sparc64" which encodes a CPU and an ABI together. This doesn't seem to
++# scale well for GMP, where exact CPU types like "ultrasparc2" are wanted,
++# separate from the ABI used on them.
++#
++#
++# The variables set here are
++#
++# cclist the compiler choices
++# xx_cflags flags for compiler xx
++# xx_cflags_maybe flags for compiler xx, if they work
++# xx_cppflags cpp flags for compiler xx
++# xx_cflags_optlist list of sets of optional flags
++# xx_cflags_yyy set yyy of optional flags for compiler xx
++# xx_ldflags -Wc,-foo flags for libtool linking with compiler xx
++# ar_flags extra flags for $AR
++# nm_flags extra flags for $NM
++# limb limb size, can be "longlong"
++# path mpn search path
++# extra_functions extra mpn functions
++# fat_path fat binary mpn search path [if fat binary desired]
++# fat_functions fat functions
++# fat_thresholds fat thresholds
++#
++# Suppose xx_cflags_optlist="arch", then flags from $xx_cflags_arch are
++# tried, and the first flag that works will be used. An optlist like "arch
++# cpu optimize" can be used to get multiple independent sets of flags tried.
++# The first that works from each will be used. If no flag in a set works
++# then nothing from that set is added.
++#
++# For multiple ABIs, the scheme extends as follows.
++#
++# abilist set of ABI choices
++# cclist_aa compiler choices in ABI aa
++# xx_aa_cflags flags for xx in ABI aa
++# xx_aa_cflags_maybe flags for xx in ABI aa, if they work
++# xx_aa_cppflags cpp flags for xx in ABI aa
++# xx_aa_cflags_optlist list of sets of optional flags in ABI aa
++# xx_aa_cflags_yyy set yyy of optional flags for compiler xx in ABI aa
++# xx_aa_ldflags -Wc,-foo flags for libtool linking
++# ar_aa_flags extra flags for $AR in ABI aa
++# nm_aa_flags extra flags for $NM in ABI aa
++# limb_aa limb size in ABI aa, can be "longlong"
++# path_aa mpn search path in ABI aa
++# extra_functions_aa extra mpn functions in ABI aa
++#
++# As a convenience, the unadorned xx_cflags (etc) are used for the last ABI
++# in ablist, if an xx_aa_cflags for that ABI isn't given. For example if
++# abilist="64 32" then $cc_64_cflags will be used for the 64-bit ABI, but
++# for the 32-bit either $cc_32_cflags or $cc_cflags is used, whichever is
++# defined. This makes it easy to add some 64-bit compilers and flags to an
++# unadorned 32-bit set.
++#
++# limb=longlong (or limb_aa=longlong) applies to all compilers within that
++# ABI. It won't work to have some needing long long and some not, since a
++# single instantiated gmp.h will be used by both.
++#
++# SPEED_CYCLECOUNTER, cyclecounter_size and CALLING_CONVENTIONS_OBJS are
++# also set here, with an ABI suffix.
++#
++#
++#
++# A table-driven approach like this to mapping cpu type to good compiler
++# options is a bit of a maintenance burden, but there's not much uniformity
++# between options specifications on different compilers. Some sort of
++# separately updatable tool might be cute.
++#
++# The use of lots of variables like this, direct and indirect, tends to
++# obscure when and how various things are done, but unfortunately it's
++# pretty much the only way. If shell subroutines were portable then actual
++# code like "if this .. do that" could be written, but attempting the same
++# with full copies of GMP_PROG_CC_WORKS etc expanded at every point would
++# hugely bloat the output.
