- Switched to automake 1.11.6, see CVE-2012-3386.
- #14669: Fixed extraction of CC from gmp.h.
- Fixed case of intermediate zero real or imaginary part in mpc_fma,
found by hydra with GMP_CHECK_RANDOMIZE=1346362345.
This is on top of the following changes from version 1.0
- Licence change towards LGPLv3+ for the code and GFDLv1.3+ (with no
invariant sections) for the documentation.
- 100% of all lines are covered by tests
- Renamed functions
. mpc_mul_2exp to mpc_mul_2ui
. mpc_div_2exp to mpc_div_2ui
- 0^0, which returned (NaN,NaN) previously, now returns (1,+0).
- Removed compatibility with K&R compilers, which was untestable due
to lack of such compilers.
- New functions
. mpc_log10
. mpc_mul_2si, mpc_div_2si
- Speed-ups
. mpc_fma
- Bug fixes
. mpc_div and mpc_norm now return a value indicating the effective
rounding direction, as the other functions.
. mpc_mul, mpc_sqr and mpc_norm now return correct results even if
there are over- or underflows during the computation.
. mpc_asin, mpc_proj, mpc_sqr: Wrong result when input variable has
infinite part and equals output variable is corrected.
. mpc_fr_sub: Wrong return value for imaginary part is corrected.
Convert to the new LIB_DEPENDS standard and remove hard-coded
.so versions from a couple of dependent ports.
Bump PORTREVISIONS of all dependent ports.

- update math/R to 2.15.0, and adjust dependent ports
- minor changes to bsd.cran.mk [2]: rename MASTER_CRAN_SITES to
MASTER_SITE_CRAN, as in bsd.sites.mk; make the install target more
flexible and allow CRAN ports to override it; add a regression-test
target; set USE_FORTRAN to match math/R; remove some of the
redundant checks of USE_R_MOD; honor NOPORTDATA and NOPORTDOCS

The snow package provides support for simple parallel computing on a
network of workstations using R. A master R process calls makeCluster
to start a cluster of worker processes; the master process then uses
functions such as clusterCall and clusterApply to execute R code on
the worker processes and collect and return the results on the master.
This framework supports many forms of "embarrassingly parallel"
computations.
Snow can use one of four communications mechanisms: sockets, PVM, MPI,
or NetWorkSpaces (NWS). NWS support was provided by Steve Weston.
PVM clusters use the rpvm package; MPI clusters use package Rmpi; NWS
clusters use package nws. If pvm is used, then pvm must be started,
either using a pvm console (e.g the pvm text console or the graphical
xpvm console, both available with pvm) or from R using functions
provided by rpvm. Similarly, LAM-MPI must be started, e.g. using
lamboot, for MPI clusters that use Rmpi and LAM-MPI. If NWS is used,
the NetWorkSpaces server must be running. SOCK clusters are the
easiest approach for using snow on a single multi-core computer as
they require no additional software.
