Test to see if a particular fix should be applied to a header file.

NOTE TO DEVELOPERS
The routines you write here must work closely with fixincl.c.
Here are the rules:
1. Every test procedure name must be suffixed with "_fix".
These routines will be referenced from inclhack.def, sans the suffix.
2. Use the "FIX_PROC_HEAD()" macro _with_ the "_fix" suffix
(I cannot use the ## magic from ANSI C) for defining your entry point.
3. Put your test name into the FIXUP_TABLE.
4. Do not read anything from stdin. It is closed.
5. Write to stderr only in the event of a reportable error
In such an event, call "exit (EXIT_FAILURE)".
6. You have access to the fixDescList entry for the fix in question.
This may be useful, for example, if there are interesting strings
or pre-compiled regular expressions stored there.
