+# This makro sets up additional library directories depending on the compiler.
+# The reason behind this are the binary incompatible libraries generated by
+# different compilers on Windows (e.g. Microsoft Visual Studio vs. Borland).
+#
+# Although newer versions of MSVC can operate with older libraries there may
+# be libs compiled for a more recent version as MSVC6. Scan through all the
+# possible directories for the matching lib.
+#
+# This makro expects the /lib directory (usually $ENV{SISODIRsomething}) as
+# argument BASEDIR and will append a list of all valid library paths to
+# variable LIB_DIRS. This may or may not include BASE_DIR depending on the
+# platform. If BASEDIR is empty or is just "/lib" nothing will happen to
+# LIB_DIRS.
+#
+# An optional variable name may be passed as third argument. If that argument
+# is given the best matching suffix will be stored in that variable (e.g.
+# "visualc2008" if you are using MSVC9). This will even work if LIB_DIRS would
