+64-bit Windows on AMD64/Intel EM64T is somewhat supported in the 7.0
+release. A collector can be built with Microsoft Visual C++ 2005.
+The resulting test programs have been known to work at least once.
+More testing would clearly be helpful.
+
+Currently only NT_X64_STATIC_THREADS_MAKEFILE has been used in
+this environment. Copy this file to MAKEFILE, and then type "nmake"
+in a Visual C++ command line window to build the static library
+and the usual test programs. To verify that the colllector is
+at least somewhat functional, run gctest.exe. This should create
+gctest.exe.log after a few seconds.
+
+This process is completely analogous to NT_STATIC_THREADS_MAKEFILE
+for the 32-bit version.
+
+Note that currently a few warnings are still generated by default,
+and a number of others have been explicitly turned off in the makefile.
