Based on the documentation, ifnames will output only the identifiers used
in #if directives. The CVS version dumps all the lines that start with
# rather than just the identifiers.
$ cat test.c
#include <stdio.h>
#if HAVE_SOMETHING
#endif
int
main(int argc, char *argv[] )
{
printf("Hello, World!\n");
}
$ ifnames --version
Autoconf version 2.14.1
$ ifnames test.c
HAVE_SOMETHING test.c
$ ifnames --version
ifnames (GNU autoconf) 2.49b

Is the documenation wrong or the new ifnames. Besides some minor changes
between the two versions, the new version has been GNU standardized.
I have un-GNU standardized the code and it works again.
I'll submit a patch to [EMAIL PROTECTED]
