[netflow-tools] CVS Snapshot Breakage

[Jesse Kempf]

Hi,
At the end of the email, I've attached the full session.
In short, compiling the CVS snapshot on FreeBSD 6.2/i386 fails with:

waffle% make
gcc -g -O2 -fPIC -c flowd.c
flowd.c: In function `usage':
flowd.c:1381: error: `PROGVER' undeclared (first use in this function)
flowd.c:1381: error: (Each undeclared identifier is reported only once
flowd.c:1381: error: for each function it appears in.)
flowd.c:1386: error: `SYSCONFDIR' undeclared (first use in this  
function)
flowd.c:1386: error: syntax error before string constant
flowd.c: In function `main':
flowd.c:1396: error: `SYSCONFDIR' undeclared (first use in this  
function)
flowd.c:1396: error: syntax error before string constant
*** Error code 1

Stop in /tmp/flowd/flowd.

It took me a little while to figure out that this wasn't my fault (I  
did a little mucking around in Makefile.in, and the autotools and I  
have never gotten along very well).

The preprocessor magic seems to be broken. I ran autoconf-2.59 and  
2.61 on configure.ac, and this happens with configure scripts  
generated by both versions.

While I'd normally have no problem going in, fixing things, and  
submitting a patch, I'm not sure exactly what the reason is for  
what's lead to the breakage.

Cheers,
-Jesse Kempf
