Here are the rules: 1. Every test procedure name must be suffixed with "_test". These routines will be referenced from inclhack.def, sans the suffix. 2. Use the "TEST_FOR_FIX_PROC_HEAD()" macro _with_ the "_test" suffix (I cannot use the ## magic from ANSI C) for defining your entry point. 3. Put your test name into the FIX_TEST_TABLE 4. Do not write anything to stdout. It may be closed. 5. Write to stderr only in the event of a reportable error In such an event, call "exit(1)". = = = = = = = = = = = = = = = = = = = = = = = = = This file is part of GCC.
