Hi Eric,
As Bernard pointed out, it is not invalid C, but instead an argument
mismatch.
It was used correctly in my program, but not the config test. Fixed.
Thank you.
(I removed the "address of" operator.) WRT ACLOCAL_AMFLAGS in the
Makefile.am file: I do not read the autotools documentation any more.
I did it once after Gary Vaughan was done auto-tooling my project, but I
don't
catch up with new stuff until something whacks me the upside of my head.
(I still use "configure.in" instead of "configure.ac", for example. I
keep meaning
to fix that....) Anyway, thank you for pointing this out (whacking my
head) :).

Duplicate the above command line, but add these two options to autogen:
--trace=everything --traceout=tracefile.txt
Once autogen reaches the "DONE" state, it does not do a whole lot.
viz., it calls "exit(3C)". I suppose you could have it call _exit()
instead??? Don't know. I've not seen a done state seg fault before.
You'll need to trace the code in "doneCheck" that gets called by
the exit code. I'm not a CygWin person, so let me know what needs
fixing. Thanks! - Bruce
P.S. you might want to play with a pre-release. It includes your two
patches, but otherwise the deltas are in different code. Thus,
it also might not matter:
http://autogen.sourceforge.net/data/autogen-5.8.8pre6.tar.gz
static void
inner_main( int argc, char** argv )
{
initialize( argc, argv );
procState = PROC_STATE_LOAD_DEFS;
ag_scmStrings_init();
readDefines();
/*
* Activate the AutoGen specific Scheme functions.
* Then load, process and unload the main template
*/
procState = PROC_STATE_LOAD_TPL;
{
tTemplate* pTF = loadTemplate( pzTemplFileName );
procState = PROC_STATE_EMITTING;
processTemplate( pTF );
procState = PROC_STATE_CLEANUP;
cleanup( pTF );
}
procState = PROC_STATE_DONE;
exit( EXIT_SUCCESS );
}
