+# - Check if the DIR symbol exists like in AC_HEADER_DIRENT.
+# CHECK_DIRSYMBOL_EXISTS(FILES VARIABLE)
+#
+# FILES - include files to check
+# VARIABLE - variable to return result
+#
+# This module is a small but important variation on CheckSymbolExists.cmake.
+# The symbol always searched for is DIR, and the test programme follows
+# the AC_HEADER_DIRENT test programme rather than the CheckSymbolExists.cmake
+# test programme which always fails since DIR tends to be typedef'd
+# rather than #define'd.
+#
+# The following variables may be set before calling this macro to
+# modify the way the check is run:
+#
+# CMAKE_REQUIRED_FLAGS = string of compile command line flags
+# CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
+# CMAKE_REQUIRED_INCLUDES = list of include directories
+# CMAKE_REQUIRED_LIBRARIES = list of libraries to link
