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.

d2d1ac2f2c Improve the logger GUI in DrRacket 
One drawback to the current situation (after this commit) is that all
log messages are sent into the user's logger, even messages that come
about as part of DrRacket's implementation. It isn't clear how to fix
this without enumerating all of the possible messages to share and
explicitly forwarding them (both of which are suboptimal things).

On the plus side, the GUI now uses the "debug@GC" notation in a text
field, and when the logger pane is not open, there is no extra work
going on. Plus other, minor GUI improvements.

8a3f662d51 git rid of thread unsafe use of load-collections-xref 
This was there, I believe, to avoid latency when clicking
on the [docs] links in the language dialog. But now that
we're using a database anyways, loading the xrefs is fast.
