12 The routines you write here must work closely with fixincl.c.
16 1. Every test procedure name must be suffixed with "_test".
17 These routines will be referenced from inclhack.def, sans the suffix.
19 2. Use the "TEST_FOR_FIX_PROC_HEAD()" macro _with_ the "_test" suffix
20 (I cannot use the ## magic from ANSI C) for defining your entry point.
22 3. Put your test name into the FIX_TEST_TABLE
24 4. Do not write anything to stdout. It may be closed.
26 5. Write to stderr only in the event of a reportable error
27 In such an event, call "exit(1)".
