311d55b5cf fix bug that affects `free-identifier=?' 
This bug is in the "amazing that it lurked for years" category,
as well as the "stupid use of C preprocessor" category.

40197835c9 repair `dynamic-require-for-syntax' 
That primitive is probably a bad idea, but maybe it's useful
until we have separaely loadable parts of a module.

1c04cf1b02 make `port-try-file-lock?' work for Solaris 
Shared locking now allowed only on input port, and exclusive
locking is allowed only on output ports, which allows an implementation
via fcntl(...,F_SETLK,...).

ec27cbfd90 fix problems related to futures and is-list flags on pairs 
Although a future thread used an atomic compare-and-swap to
set "is a list" or "not a list" flag on pairs via the
JIT-implemented `list?', the hashing function in the runtime
thread did not; as a result, it might be possible to lose
a hash code due to cache inconsistency (although I'm not
sure it's actually possible, and I couldn't trigger a problem
with a test). Most of the changes are related to using
an atomic compare-and-swap when setting a hash code, as
well as clean-ups to related code. Processor-count tests
avoid using atomic compare-and-swap on uniprocessors, which
might not support the relevant machine instructions.

As significantly, the compare-and-swap operation for the
JIT-implemented `list?' did not actually set flags on
a pair that has a hash code. This could lead to `list?'
tests that were not constant time (but only if the relevant
pair's `eq?' hash code had been used previously).

compilation should be platform-independent.

c9d4e0fb8c win32: fix `copy-file' handling of file-exists error 
The specific error reported by CopyFileW doesn't seem
to be documented. It's unclear whether Racket's old test
for ERROR_EXISTS_ALREADY was the wrong choice (as opposed
to ERROR_FILE_EXISTS) or whether some Windows versions
use it; we test for both for now.

Also, improve error reporting when an errno or
GetLastError() value is available.

to break in some cases.

09eab9c3eb fix JIT problem that can break futures 
A recent (weeks-old) JIT change set one of a function's code
 pointers to NULL to indicate that JIT-compilation of the
 function is in progress, but that breaks futures. Set the
 code pointer to a different not-yet-ready function, instead.
