+ extremely unlikely circumstances. Thanks to Jean-Baptiste Nivois for
+ some careful code reading.
+ - Added support for kFreeBSD + glibc (Thanks to Petr Salinger)
+ - Fix more MacOS threads memory leaks (Thanks to Allan Hsu)
+ - Added initial Solaris/X86-64 support (Thanks to Rainer Orth)
+ - Applied a long-lost MINGW patch from Gerard Allan for malloc redirection
+ with threads. This one probably makes no sense for 7.0, and was not applied
+ there.
+ - The Solaris/SPARC definition of GC_INIT() in gc.h wasn't C++-compilable.
+
To do:
- The USE_MUNMAP code should really use a separate data structure
indexed by physical page to keep track of time since last use of
