-The above macros probably contain references to shell variables.
+The above macros may contain references to shell variables.
 
 The cause of this problem is usually that in a configure.ac or
 configure.in file, there is some code like
 
-    FOO_DIR=\"\${bindir}\"
-    AC_DEFINE_UNQUOTED(FOO_DIR, \"\$FOO_DIR\", [Directory where foo files go])
+    FOO_DIR="\${bindir}"
+    AC_DEFINE_UNQUOTED(FOO_DIR, "\$FOO_DIR", [Directory where foo files go])
 
 You can fix this by telling the original package author not to use
 AC_DEFINE_UNQUOTED for directories. Instead, {he,she} should do
 something like this:
 
     # in configure.ac:
-    foodir=\"\${bindir}\"
+    foodir="\${bindir}"
     AC_SUBST(FOO_DIR)
 
     # in the Makefile.am files (can be more than one):
-    AM_CPPFLAGS= -DFOO_DIR=\\\"@FOO_DIR@\\\"
+    AM_CPPFLAGS= -DFOO_DIR=\\"@FOO_DIR@\\"
+
+If this check is wrong and the package really wants to have "\${" in the
+macros, append the above filenames to the CHECK_HEADERS_SKIP variable in
+the package Makefile.
