#
-# - COMPAT=/DAUTO_WINSOCK
+# - COMPAT=/DAUTO_WINSOCK (Windows only)
# Causes PuTTY to assume that <windows.h> includes its own WinSock
# header file, so that it won't try to include <winsock.h>.
#
-# - COMPAT=/DWINSOCK_TWO
+# - COMPAT=/DWINSOCK_TWO (Windows only)
# Causes the PuTTY utilities to include <winsock2.h> instead of
# <winsock.h>, except Plink which _needs_ WinSock 2 so it already
# does this.
#
-# - COMPAT=/DNO_SECURITY
+# - COMPAT=/DNO_SECURITY (Windows only)
# Disables Pageant's use of <aclapi.h>, which is not available
# with some development environments (such as older versions of
# the Cygwin/mingw GNU toolchain). This means that Pageant
# will run fine on Win95-series OSes where there is no access
# control anyway).
#
-# - COMPAT=/DNO_MULTIMON
+# - COMPAT=/DNO_MULTIMON (Windows only)
# Disables PuTTY's use of <multimon.h>, which is not available
# with some development environments. This means that PuTTY's
# full-screen mode (configurable to work on Alt-Enter) will
# build, since at the time of writing this <multimon.h> is
# known not to be available in Cygwin.
#
+# - COMPAT=/DNO_MANIFESTS (Windows only)
+# Disables inclusion of XML application manifests in the PuTTY
+# binaries. This may be necessary to build for 64-bit Windows;
+# the manifests are only included to use the XP GUI style on
+# Windows XP, and the architecture tags are a lie on 64-bit.
+#
# - COMPAT=/DNO_IPV6
# Disables PuTTY's ability to make IPv6 connections, enabling
# it to compile under development environments which do not
# support IPv6 in their header files.
#
-# - COMPAT=/DMSVC4
+# - COMPAT=/DMSVC4 (Windows only)
# - RCFL=/DMSVC4
# Makes a couple of minor changes so that PuTTY compiles using
# MSVC 4. You will also need /DNO_SECURITY and /DNO_MULTIMON.
#
-# - RCFL=/DASCIICTLS
+# - RCFL=/DASCIICTLS (Windows only)
# Uses ASCII rather than Unicode to specify the tab control in
# the resource file. Probably most useful when compiling with
# Cygnus/mingw32, whose resource compiler may have less of a
# Causes PuTTY to emit a file called putty_mem.log, logging every
# memory allocation and free, so you can track memory leaks.
#
-# - XFLAGS=/DMINEFIELD
+# - XFLAGS=/DMINEFIELD (Windows only)
# Causes PuTTY to use a custom memory allocator, similar in
# concept to Electric Fence, in place of regular malloc(). Wastes
# huge amounts of RAM, but should cause heap-corruption bugs to
