comment out LICENESE for now.

Log message:
Update to version 4.2.2.  Support DESTDIR installation.  Add option
to build a "fat" binary on (${MACHINE_ARCH} == "i386" \ 
&& ${OPSYS} != "Darwin").
This isn't enabled by default now, but it might be useful for build builds,
as it uses cpuid at runtime to choose the most appropriate assembler code.
Insofar as I can tell, no BUILDLINK_A[BP]I_DEPENDS bump is necessary.

NOTE: Support for Darwin-*-i386 and Darwin-*-x86_64 has been improved,
see below.  Thus, I recommend that we test building the assembler code
on Darwin at some point.

Changes between GMP version 4.2.1 and 4.2.2:
	* License is now LGPL version 3.
Bugs:
	* Shared library numbers corrected for libcxx.
	* Fixed serious bug in gmpxx.h where a=a+b*c would generate garbage.
	  Note that this only affects C++ programs.
	* Fix crash in mpz_set_d for arguments with large negative exponent.
	* Fix 32-bit ABI bug with Itanium assembly for popcount and hamdist.
	* Fix assembly syntax problem for powerpc-ibm-aix with AIX
	  native assembler.
	* Fix problems with x86 --enable-fat, where the compiler where told to
	  generate code for the build machine, not plain i386 code as it should.
	* Improved recognition of powerpc systems wrt Altivec/VMX capability.
	* Misc minor fixes, mainly workarounds for compiler/assembler bugs.
Speedups:
	* "Core 2" and Pentium 4 processors, running in 64-bit mode will get a
	  slight boost as they are now specifically recognized.
Features:
	* New support for x86_64-solaris
	* New, rudimentary support for x86-apple-darwin and x86_64-apple-darwin.
	  (Please see http://gmplib.org/macos.html for more information.)

Fix abusers of LOWER_OPSYS to check OPSYS or MACHINE_PLATFORM instead.

Log message:
Don't use x86 assembly on Darwin, as it doesn't build.

Update to GNU MP 4.2.1

Changes between GMP version 4.2 and 4.2.1

  Bugs:
  * Shared library numbers corrected.
  * Broken support for 32-bit AIX fixed.
  * Misc minor fixes.

  Speedups:
  * Exact division (mpz_divexact) now falls back to plain division for large
    operands.

  Features:
  * Support for some new systems.

Changes between GMP version 4.1.4 and 4.2

  Bugs:
  * Minor bug fixes and code generalizations.
  * Expanded and improved test suite.

  Speedups:
  * Many minor optimizations, too many to mention here.
  * Division now always subquadratic.
  * Computation of n-factorial much faster.
  * Added basic x86-64 assembly code.
  * Floating-point output is now subquadratic for all bases.
  * FFT multiply code now about 25% faster.
  * Toom3 multiply code faster.

  Features:
  * Much improved configure.
  * Workarounds for many more compiler bugs.
  * Temporary allocations are now made on the stack only if small.
  * New systems supported: HPPA-2.0 gcc, IA-64 HP-UX, PowerPC-64 Darwin,
    Sparc64 GNU/Linux.
  * New i386 fat binaries, selecting optimised code at runtime (--enable-fat).
  * New build option: --enable-profiling=instrument.
  * New memory function: mp_get_memory_functions.
  * New Mersenne Twister random numbers: gmp_randinit_mt, also now used for
    gmp_randinit_default.
  * New random functions: gmp_randinit_set, gmp_urandomb_ui, gmp_urandomm_ui.
  * New integer functions: mpz_combit, mpz_rootrem.
  * gmp_printf etc new type "M" for mp_limb_t.
  * gmp_scanf and friends now accept C99 hex floats.
  * Numeric input and output can now be in bases up to 62.
  * Comparisons mpz_cmp_d, mpz_cmpabs_d, mpf_cmp_d recognise infinities.
  * Conversions mpz_get_d, mpq_get_d, mpf_get_d truncate towards zero,
    previously their behaviour was unspecified.
  * Fixes for overflow issues with operands >= 2^31 bits.

  Caveats:
  * mpfr is gone, and will from now on be released only separately.  Please see
    www.mpfr.org.

Log message:
Instead of setting compiler flags in each package if it uses C99,
allow USE_LANGUAGES+=c99 and let gcc and mipspro do the right thing.
May need to be reviewed/added for other compilers.

corrected LOWER_OPSYS matching for IRIX 5

Log message:
Change the format of BUILDLINK_ORDER to contain depth information as well,
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.

For example, "make show-buildlink3" in fonts/Xft2 displays:

	zlib
	fontconfig
	    iconv
	    zlib
	    freetype2
	    expat
	freetype2
	Xrender
	    renderproto

Log message:
Track information in a new variable BUILDLINK_ORDER that informs us
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.
