Problem with -v option (bug?)

Hi,
My system is Slackware 10 with gawk 3.1.3
When I run (in a bash) command
> cat times | awk --source '{akt=$1*100+$2*(1.67)
> print akt}'

where times is
----times----
00 06
05 11
00 32
10 23
-----end-----

I get:
10,02
518,37
53,44
1038,41

which is what I expect to get (times is HOURS MINUTES \n, output is hom
much shoud user pay for using computer...)

Now, when I run
> cat times | awk -v b=4 --source '{akt=$1*100+$2*(1.67)
> print akt}'
I get
6
511
32
1023

That is, gawk doesn't allo any floating point calculation. Why is that?
Is it possible it's a gawk-bug?

Best regards,
sirix.

I hate bottom posting, but since everyone here will yell at me if I
don't, what the heck. I've posted a fix in bug-gnu-utils group, but
here it is in case anyone else wants it.

Thanks,

Arnold

Ok, it works now allright. Normally I use LC_ALL=pl_PL. I'm going to
download and compile 3.1.4 - as soon as I've done it I write you an
email with results.
Just in case anybody bothers with that in future - I send this post also
to c.l.awk newsgroup.

I really appreciate your help, thanks very much.
