+# makensis for the given architecture.
+#
+# makensis is a program for the host system, but MXE installs it into the
+# target prefix - usr/<target>/bin - because the installer stubs it carries are
+# built for that target: the copy from the x86_64-w64-mingw32.shared tree emits
+# 64 bit installers, the one from the i686-w64-mingw32.shared tree 32 bit ones,
+# and a 64 bit installer does not run on a 32 bit Windows. So the copy
+# belonging to the architecture being packaged is used when it is there, any
+# other MXE built copy after that, then usr/bin/makensis for an nsis built into
+# the MXE tree by hand, and finally whatever the host system has.
+#
+# usr/<target>/bin is deliberately not added to PATH: it is full of Windows
+# executables, and configure --host=<target> looks for host programs with the
+# .exe suffix as well, so a Windows uic.exe or sqlite3.exe in there could be
+# picked up as if it were a host tool.
