f5fa93572d Moar `math/matrix' review/refactoring 
* Gram-Schmidt using vector type

* QR decomposition

* Operator 1-norm and maximum norm; stub for 2-norm and angle between
  subspaces (`matrix-basis-angle')

* `matrix-absolute-error' and `matrix-relative-error'; also predicates
  based on them, such as `matrix-identity?'

* Lots of shuffling code about

* Types that can have contracts, and an exhaustive test to make sure
  every value exported by `math/matrix' has a contract when used in
  untyped code

* Some more tests (still needs some)

03259ef539 MinGW-w64 support 
For now, SGC must be used, but `configure' does not select it
automatically.

Also, support Cygwin (in addition to MSYS) as a build environment
when using MinGW compilers. Since I build in a Cygwin environment
(which seemed to be the easiest way to get MinGW-w64 gcc), I use

  ../configure --host=x86_64-w64-mingw32 --enable-sgc

e55a31480e Precise flonum tests (error usually must be <= 0.5 ulp), and prerequisite 
additions/changes

* More accurate `flulp-error'

* Added `flonum->fields', `fields->flonum', `flonum->sig+exp',
  `sig+exp->flonum' (currently undocumented)

* Correctly rounded, robust `bigfloat->fl2' and `fl2'

* Correctly rounded, robust `fl+/error', `fl-/error', `fl*/error',
  `flsqr/error', `fl//error'

* Much faster but slightly less accurate fl2 ops (shamelessly stolen from
  crlibm, which is LGPL)

* Added `fl2ulp', `fl2ulp-error', `fl2?' (which detects overlap),
  `+max-fl2-subnormal.0' (which was tricky), `fl2abs'

* Added deterministic and randomized flonum op tests (against MPFR)

* Added deterministic and randomized flonum/error op tests (against MPFR)

* Added deterministic and randomized fl2 op tests (against MPFR)

* Exposed FPU tests in `math/utils' (currently undocumented)

f2d870859a logging: allow name in `log-message', report it in a log-receiver evt 
The synchronization result of a log receiver is now a vector of four
values, instead of three, where the last one reports the name.

Also, an optional argument to `make-logger' provides a notification
callback for each event sent to the logger.

These changes enable more control over loggers and events. Suppose
that you have processes A and B, and you want all log events of A
to be visible to B, but not vice-versa. Furthermore, you want the
log events to appear at B in the right order: if A logs an event
before B, then A's event should arrive at a log receiver's before
B's. Now that a log receiver gets the name associated with the
original event, and now that the name can be re-sent in a
`log-receiver', it's possible to give A and B separate loggers and
send all of the events from A's logger to B's logger. Furthermore,
you can use the notification callback so that when an event is logged
in B, you can make sure that all available events from from A's
logger have been transferred to B's logger.
