   Attached is the "inclhack.sh" generated script for your possible
   assistence.

The only problem I saw in a quick glance is that using functions in sh
scripts is unfortunately nonportable.

In general, this seems like a very promising approach.  It would be
nice if people on different systems could compare this to the
traditional fixincludes script.

You can run
    fixincludes foo /usr/include
to fix the header files in /usr/include into the directory foo.  If
you do that with the traditional fixincludes and with Bruce's new
inclhack script, we can see whether inclhack does the same thing.  Any
differences would presumably require investigation.

	2.  The commentary to the right of "#else" and "#endif" used to
	    be stripped.  I put it inside "/* */".

Trying to modify what fixincludes does is always a risky business.

What if this commentary includes a comment?  If you have
	#endif foo /* stuff */
you then get nested comments and we still get a warning with -pedantic.

Looking through the ChangeLogs, I see that we did indeed run into a problem
with this, though it is not the first case I thought of.  Consider this
example
	/* Comment out this stuff
        #ifdef foo
	...
	#endif foo
	end of comment.  */
If you fix the foo by changing it to /* foo */, then you now have a nested
comment.  This is worse than what we started with, because this is now a
syntax error regardless of what options are used.

	* fixinc.svr4: Remove everything after #endif, instead of trying
        to turn it into comments, which loses inside comments.
        * fixincludes: Likewise.  Remove #endif workarounds for Ultrix 4.[12]
        and SunOS 4.1, which are no longer needed because of this bug fix.

I am not a portable shell expert.  In fact, I mostly use ksh.
Anyway, I'll regen it and embed it inside the main loop
for anyone that needs it that way.

Thanks.  This is what I was hoping people would do.

> Any differences would presumably require investigation.

I can tell you of two that I know about:
1.  the "#undef NULL" inserted before "#define NULL" is left-justified
2.  The commentary to the right of "#else" and "#endif" used to
    be stripped.  I put it inside "/* */".

After the email traffic this past week, I decided to look at
what fixincludes was really doing, partly because it looked
like it might be prone to a development approach I have been
playing with.  What I found was:

1.  The egrep pattern used to select files for ansification of
    machine names always selected every file.

2.  The files are read in over and over in long lists.
    All processing of a single file should be done all at once
    so the file system cache can do its thing.

So, I used some editing magic and a little sweat (~2hrs) to extract
the 80 or so hacks into their fundamental descriptions.  These
descriptions consist of the list of files they might apply to,
tests to run to see if they should be attempted and the sed
or shell scripts needed to implement the hack.  From these
descriptions, I generated an equivalent shell script that addressed
issue #2.  I then simplified and separated the "#else", "#endif",
ansified machine names and the IO macro fixes to address #1.
The result works on my box.  If this script is found to work
generally (or found to work with minor mods), then I can *trivially*
generate a C program that does exactly the same thing.
At that point, I would be able to generate *BOTH* a shell script
and a C program from a *SINGLE* description of the needed changes.
Furthermore, the description file can work with the "config.h"
header file to omit the irrelevent tests.

Attached is the "inclhack.sh" generated script for your possible
assistence.
Also attached is the "inclhack.def" file, for your amusement.
