+Subject: [PATCH] Fixes #318.
+
+Eliminated the use of "class" as an identifier, as this will clearly cause
+problems if JasPer headers are used in C++ source code.
+
+In order to catch incompatibilities with C++ in the future, a trivial C++
+test program has been added.
+The CMake build process was adjusted to (optionally) allow the use of a
+C++ compiler.
+Each use of add_compile_options that sets C compiler options was changed
+to use a new function called add_c_compile_options that only sets options
+for the C compiler.
+Some changes to the CMake module for code sanitizers were made in order to
+handle the C++ compiler case.
+Several new options were added to the build script.
