README.win64

64-bit Windows on AMD64/Intel EM64T is supported.  A collector can be built
with Microsoft Visual C++ 2005 or with mingw-w64 gcc.

NT_MAKEFILE has been used in this environment.  Type
"nmake -f NT_MAKEFILE cpu=AMD64 nodebug=1" in a Visual C++ command line
window to build the release variant of the dynamic library with threads
support.
To verify that the collector is at least somewhat functional,
type "nmake -f NT_MAKEFILE cpu=AMD64 check" to build and run the usual test
programs.  This should create gctest.gc.log after a few seconds.

cpptest.exe might not run correctly in case of dynamic GC linking.  (It seems
that we're getting wrong instances of operator new/delete in some cases.)

This process is completely analogous to NT_MAKEFILE usage
for the 32-bit library version.

A similar procedure using NT_MAKEFILE is applicable to build the static
library - just pass "enable_static=1" as an extra argument to nmake.
If needed, it is also possible to build the library without threads
support - this could be done by passing "disable_threads=1" argument to nmake.

Note that some warnings have been explicitly turned off in the makefile.

VC++ note: to suppress warnings -D_CRT_SECURE_NO_DEPRECATE is used.

gcc note: -fno-strict-aliasing should be used if optimizing.
