+OMG INTERFACE DEFINITION LANGUAGE COMPILER FRONT END: KNOWN PROBLEMS
+-==================================================================-
+
+INTRODUCTION
+
+This file describes what configurations are known to work correctly with
+this release, and what are the known problems with this release as shipped.
+Comments about future possible enhancements do not imply a commitment on
+the part of Sun or any of its subsidiaries to produce these enhancements.
+
+TESTED CONFIGURATIONS
+
+This release has been tested and is known to operate correctly on:
+
+- Sparcstation 2 running SunOS 4.1.2, when compiled with SparcWorks 3.0
+- Sparcstation 10 running Solaris 2.3, when compiled with SparcWorks 3.0.1
+- Sparcstation 10 running Solaris 2.3, when compiled with SparcWorks 4.0
+
+We are aware of a bug in GNU C++ (the latest version we tested was 2.5)
+which causes up-casting (changing the type of an instance from a base class
+to a more derived class, also known as "narrowing") to fail or cause a
+program crash.
+
+PROBLEMS:
+
+This is a list of known problems with the current version of the CFE:
+
+- The following syntax, although legal, is not accepted by the CFE:
+
+  .. sequence <string <10>> ..
+
+  This causes a parse error. The cause of this problem is that the '>>' is
+  read as a right shif operater and not as two '>'s. You can avoid this
+  problem by instead writing
+
+  .. sequence <string <10> > ..
+
+- The following syntax, although legal, is not accepted by the CFE:
+
+  const string foo = "abc" " and" " another" " string";
+
+  Instead, write:
+
+  const string foo = "abc and another string";
+
+- The printout produced by the -d option for dumping the AST is not always
+  perfect. Specifically, dumping of sequences and arrays is deficient.
+
+POSSIBLE FUTURE ENHANCEMENTS:
+
+This is a list of areas in which the code of the CFE may change in future
+releases:
+
+- The current release is restricted in its use of C++ because it must
+  be possible to compile it using C++ 2.1. However, we have also provided
+  files that depend on features which are only present in C++ 3.0, such as
+  templates. If your compiler supports templates and you wish to use them,
+  copy the files in include/utl_tmpl to include, and copy the files in
+  util/utl_tmpl to util. You will also need to make compiler dependent
+  modifications to Makefiles throughout the CFE directory hierarchy to
+  enable the use of templates.
+
+  The code using templates was donated by Steve Vinoski of HP.
+
+  In a future release of the CFE only the template code may be included,
+  and hence users will need to use a C++ 3.0 or higher compiler.
+
+- The UTL_list classes defined in the util directory are rudimentary. More
+  features may be added to make the functionality richer.
+
+- The UTL_String class may be rewritten or replaced by a standard ANSI C++
+  String implementation. Applications will be shielded from this change.
