- * Fix for Radar bug 2200596 --
- * EH symbol definitions for gcc 2.7.2.x implementation of
- * C++ exception handling.  The problem:  the EH implementation
- * has "throw" store stuff into these pointers, and then as the
- * stack is unwound, the code generated into each function (for
- * checking whether this function contains a relevant "catch"
- * clause and for calling destructors for local variables) looks
- * at these globals to find the type and value thrown.
- *
- * The problem was that the compiler generated the symbols as
- * "common" symbols, and common symbols cannot be placed in
- * dynamic shared libraries.  So we must put these guys as
- * "data" symbols into crt0.o or the System Framework (library),
- * and the compiler must generate code that defines the symbols
- * as external references instead of common.
- *
- * I changed the symbol names (added the "_272") to be utterly
- * paranoid about any possible future use of similar names by
- * any future versions of gcc.
