+#### When building with MinGW inside the MSYS tree, 'pwd' produces
+#### directories relative to the root of the MSYS tree,
+#### e.g. '/home/user/foo' instead of '/d/MSYS/home/user/foo'.  When
+#### such a value of srcdir is written to the top-level Makefile, it
+#### gets propagated to src/epaths.h, and that causes temacs to fail,
+#### because, being a MinGW program that knows nothing of MSYS root
+#### substitution, it cannot find the data directory.  "pwd -W"
+#### produces Windows-style 'd:/foo/bar' absolute directory names, so
+#### we use it here to countermand that lossage.
