Further, he says that it will get into a new cvxopt release, 1.1.3, due
shortly.

to complete the investigation of this problem myself. I've checked and it
gets rid of the warnings on FreeBSD as well. That leaves only just over
3000 warnings in a Sage build that need investigating.

reasonable. I would appreciate the new SPKG including my fix to support
FreeBSD (and something similar may be needed to support Cygwin)
New spkg is here:
http://boxen.math.washington.edu/home/dima/packages/cvxopt-1.1.2.spkg
here is the list of goodies that got added/updated/fixed:
* applied P.Jeremy's FreeBSD patch
* corrected the 64-bit specific int* bug reported by pjeremy
* turned on GSL extension (this is the default mode for CVXOPT, and GSL
is a standard Sage spkg, so
this makes perfect sense); this in particular allowed to get rid of
strange random seed-related
import bugs uncovered by David Kirkby's spkg-check
TODO(?): one might want to enchance the code to allow other Sage random
sources,
at the moment only GSL is used in CVXOPT-1.1.2 spkg, apparently it
will need an unclear
to me "with seed(..)" construct.
TODO: We will need to make sure that CVXOPT is built after GSL
* modified spkg-check to report test names, cd to appropriate subdirs,
and skip .bin files.
TODO: add more tests.
* corrected the .patch files in patches/ to be in right order --- just
run the makepatchfiles
script to re-create these files!
* removed html doc files in src/doc; the .rst doc files are there, so
it's a question of
rebuilding them
(e.g. one can do sage -sh; cd src/doc; make html)
TODO: incorporate docs buiding into spkg-install, and/or merge into
Sage documentation
* included David's shortened and gcc-version targeted Sun-specific patch
(comment 88); removed sun_complex.h
* took care of SPKG.txt sections, as mentioned in comment 87
MAJOR change:
it now depends on GSL--- this gets rid of sage.prandom related problems
MAJOR TODOs:
MacOSX fixes, and testing with gcc-4.5 on as many platforms as possible
(otherwise it looks good to go !)
