ifnames output

[Paul Martinolich]

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 address@hidden
